Washington Nationals right-hander Joe Ross will miss the rest of the season but won't need surgery for his partially torn ulnar collateral ligament at this time, manager Dave Martinez said Tuesday.

Instead, Ross will rest his injury and "go through some extensive rehab" with the hope he can return to pitch in the spring, Martinez said.

Ross was examined by Dr. Keith Meister, who performed Ross' Tommy John surgery in 2017.

Ross had felt tightness in his right forearm after a bullpen session on Saturday and had an MRI that showed the partial tear of his ulnar collateral ligament. The Nationals sent Ross to Meister to determine whether a second Tommy John surgery was required. He was placed on the injured list Sunday.

"Of course, he's not going to be happy because he wanted to continue to pitch, but I think that's great news," Martinez told reporters, according to MASN Sports. "We'll get him the rest that he needs and then get him back on the mound as soon as we can. But I don't expect him at this point to pitch any more this year. We want to make sure he's completely healthy, and he's ready to go in spring training."

Ross has been the Nationals' most consistent starter this season apart from Max Scherzer, who was traded to the Los Angeles Dodgers at the deadline. The 28-year-old Ross is 5-9 with a 4.17 ERA in 20 starts, with career highs in innings pitched (108) and strikeouts (109) in 20 games (19 starts).

Toronto Blue Jays outfielder George Springer was placed on the 10-day injured list Tuesday with a sprained left knee.

Blue Jays manager Charlie Montoyo, speaking to reporters before Toronto played the Washington Nationals, was unsure of any type of timeline for Springer to rehabilitate and return, though Montoyo said he hoped he could play before the regular season ends. The move is retroactive to Sunday.

On Saturday, Springer left a road loss to the Seattle Mariners in the seventh inning when he collided with the outfield wall trying to make a catch. It only added to a season of frustration for the 31-year-old, who landed on the injured list two other times in his first season with the Blue Jays.

All that said, when healthy, Springer has provided the boost Toronto was hoping for when they signed him as a free agent last offseason. He has played in just 49 games, but is hitting .269 with 16 home runs and 35 RBIs.

Corey Dickerson figures to see his playing time increase in the outfield with Springer out. In Sunday's series-ending win over Seattle, Dickerson, who started in center field, scored three runs, finishing with two hits and an RBI.

To fill the roster spot, Toronto recalled infielder Otto Lopez from Triple-A Buffalo.

CHICAGO -- Oakland Athletics ace Chris Bassitt was carted off the field in the second inning of Tuesday night's game against the Chicago White Sox after being hit in the head by a line drive.

Bassitt was "conscious and aware," the A's said in a tweet, adding that he was being taken to a local hospital.

Bassitt, 32, immediately fell to the ground after being struck by the ball, which came off White Sox center fielder Brian Goodwin's bat at 100.1 mph.

Teammates as well as the A's training staff rushed to his aid at the mound, where Bassitt remained down for several minutes. He was helped onto a golf cart and taken off the field.

Bassitt, who is 12-3 with a 3.06 ERA this season, was replaced by reliever Burch Smith.

LOS ANGELES -- An attorney for Trevor Bauer asked a woman Tuesday why she left out "dozens of key facts" in her petition for a five-year restraining order against the Los Angeles Dodgers pitcher.

"I don't know," answered the woman, who testified that Bauer choked her until she was unconscious and punched her repeatedly in two sexual encounters.

The exchange during lawyer Shawn Holley's cross-examination of the woman came in her second day of testimony at the hearing in Los Angeles Superior Court.

Holley challenged the 27-year-old San Diego woman on why she omitted a text message to Bauer before their meetings saying she would have her "feelings turned off" and joking that she would have a nondisclosure agreement "signed and sealed" when she came to see him.

The woman said she no longer had access to those texts.

Holley asked why she got back into bed and slept next to Bauer after the traumatic experience she testified that she had. The woman said she wanted to remember the hours of emotional connection the two had experienced beforehand.

"I didn't want to think about what just happened," the woman said. "I wanted to go back to the way it was before we had sex."

The hearing is expected to continue Wednesday and Thursday, and to include testimony from Bauer, 30, who was placed on paid administrative leave on July 2 by Major League Baseball. The leave has been extended through Friday. MLB says it is conducting its own investigation, and Bauer could face punishment under baseball's domestic violence policy.

Holley said during her opening statement that the woman gave Bauer every indication she consented to the treatment she received during the nights they spent together at his home in Pasadena.

Under questioning from her own attorney, the woman testified that her horror grew as bruises emerged and her pain surged the day after the second time she saw Bauer, in May.

The 27-year-old said she sent Bauer a picture of herself after returning home to San Diego.

"I could not believe what my face looked like," she said. "I wanted him to know what he'd done to me."

Bauer replied in a text message, "damn girl, are you OK?"

The woman said she was just as frightened of the social consequences as the physical ones and was at first determined to tell no one else.

"I knew how that was going to go," she testified. "That situation paints me as the slut. I didn't want the story to go anywhere."

But a visit with her best friend, who was "mortified' by how she looked, convinced her to seek medical help. She would end up in a hospital emergency room, she said, which led to visits from a social worker, her parents and Pasadena police, who are still investigating three months later.

On Tuesday, she discussed the aftermath of the second visit, in which according to her testimony Bauer had punched her in the face and vagina, and left bruises on her gums, around her eyes and behind her ears.

She said she was frightened at what Bauer might have done to her while she was unconscious. In text messages and a phone call she made to him for Pasadena police to record, he said that he only punched her in the buttocks during that time.

She described an hours-long sexual assault exam that she said was terribly traumatic and physically painful.

The nurse who conducted the examination took the stand and testified Tuesday that she had never seen the kind of bruising she documented on and around the woman's vagina in the approximately 75 similar exams that she had done.

Nurse Kelly Valencia said, "it was frankly alarming," but did not think it required further treatment.

The woman testified that she received daily messages from Bauer, expressing his concern.

"Here for you if you want to talk," one read.

"I feel so bad that this happened," another said.

He offered to send her groceries while she was recovering at home, or otherwise help.

The woman said she appreciated his acknowledgement at first.

"It felt good to hear that he felt bad," she said.

But she found the messages increasingly disconcerting, and she worried that he knew she had talked to police.

"I felt like he was saying these things so I would shut up," she testified.

The Associated Press does not typically identify people who say they have been victims of sexual assault.

Bauer agreed to a $102 million, three-year contract to join his hometown Dodgers earlier this year after winning his first Cy Young with the Cincinnati Reds last season.

The NHL will have advertising on the front of team jerseys for the first time starting in the 2022-23 season, a source told ESPN.

The league's board of governors formally voted this month to approve jersey advertisements. The NHL had surveyed its teams and found the majority of them in favor of jersey ads. The ads will be featured in a 3-inch-by-3.5-inch rectangle, which is larger than the NBA's 2.5-by-2.5-inch space for uniform ads.

The news was first reported by Sportico.

Earlier this year, the NHL started exploring the revenue possibilities for jersey advertisements. NHL commissioner Gary Bettman said in June that the NHL had no plans for jersey ads in the upcoming 2021-22 season, but left the door open for future advertising.

"I wouldn't necessarily say it's inevitable. It's something that makes good sense for us to be considering and looking at. But certainly not for next season. What happens beyond that, I'm not prepared to predict," Bettman said.

The NHL has allowed ads on practice jerseys dating back to 2010. It also had corporate logos on the shoulders of World Cup of Hockey jerseys in 2016, a tournament it co-produced with the NHL Players' Association.

For years, Bettman had been hesitant to have advertising on NHL game uniforms, despite advertising on jerseys being prevalent in minor leagues such as the AHL and ECHL, and in leagues overseas. In 2015, Bettman said the NHL "certainly won't be the first" sports league to allow the jersey ads, adding that "you'd have to drag me kicking and screaming" to permit them.

But when the NBA allowed ads on its uniforms in 2017, it became inevitable that the NHL would follow, especially with the COVID-19 pandemic necessitating that the league open new revenue streams. It allowed helmet advertising for the 2020-21 season, and Bettman indicated that teams would continue with that program. He said that teams "retained more than $100 million in revenue" thanks to innovations like the helmet ads.

A source told ESPN that it's likely the placement of the ads on jerseys will be left up to individual teams. Some sweaters would favor one spot over another due to their design: Consider, for example, the New York Rangers' diagonal lettering.

SEATTLE -- The Seattle Seahawks and Jamal Adams have agreed to a four-year extension that makes him the NFL's highest-paid safety, agents Kevin Conner and Robert Brown of Universal Sports told ESPN's Adam Schefter on Tuesday.

Adams' deal carries a max value of $72 million, a $20 million signing bonus and $38 million guaranteed, the agents told Schefter.

He reported on time for training camp but has not taken part in any practices or games, watching from the sideline while appearing engaged and in good spirits. The agreement ends the three-week stalemate with the Seahawks, who open their season on Sept. 12 against the Indianapolis Colts.

Adams was a first-team All-Pro selection in 2019 and has been named to the Pro Bowl in each of the last three seasons. He set the league's single-season record for sacks by a defensive back last year with 9.5. That figure led the team, as did his 14 tackles for loss and his 30 pressures which, according to ESPN Stats & Information research, were 14 more than any other defensive back in the league.

He missed four games with a groin injury and played through injuries to both shoulders (including a torn labrum that needed surgery), two broken fingers (which also needed surgery) and a hyperextended elbow.

Coach Pete Carroll said in June that the Seahawks were counting on Adams showing up to training camp even if the two sides had yet to reach a deal by then.

Adams, 25, had joined many of his teammates in skipping the voluntary offseason program -- several veteran players did not take part until the final week -- and was excused from mandatory minicamp so he could tend to a family matter.

He was set to make $9.86 million in 2021, the final year of the rookie contract that he signed with the New York Jets as the No. 6 pick in 2017.

The Seahawks inherited that contract when they acquired Adams last summer for a package of picks that included Seattle's first-rounders in 2021 and '22, making it their boldest trade of the Carroll/general manager John Schneider era.

At the time of the trade, the Seahawks were upfront with Adams, who had requested the trade from the Jets, in that they weren't going to extend him right away. That was because they wanted to have a better sense of how much the NFL's salary cap would drop in future seasons due to the coronavirus pandemic before negotiating such a massive deal. They also wanted to get to know Adams before paying him.

According to ESPN Stats & Information research, the Adams trade marked only the fifth time since 2009 that a team gave up multiple first-round picks for a player.

Adams becomes the third player to get an extension from the Seahawks this offseason, joining receiver Tyler Lockett and punter Michael Dickson.

While Adams' deal is done, the Seahawks still have another contract dispute on their hands with 14-year veteran Duane Brown. The Pro Bowl left tackle, who turns 36 later this month, has also been present but not practicing because he's seeking an extension as he enters a contract year. All indications are that the Seahawks are not inclined to extend Brown this year.

NEW YORK -- Kemba Walker is a guy who is known for having a constant smile on his face.

But, even for him, Walker was downright giddy Tuesday morning -- and understandably so -- as he was introduced as the new starting point guard for his hometown New York Knicks here at Madison Square Garden, alongside fellow new addition Evan Fournier.

Walker's feelings came not only from getting the chance to come back home, and play in the arena where he burnished his credentials as a bonafide New York City legend playing first for Rice High School and then the University of Connecticut, but also for having an opportunity to prove the knee issues that plagued him last season in Boston are behind him.

"It means everything," Walker said of the motivation to prove he can still be an elite player in the NBA. "It's driving everything. Because I know what kind of player I am.

"I know what level I want to be at. It's added motivation."

For the Knicks, the acquisition of Walker was a chance to trumpet the return of a New York City icon to Madison Square Garden. But it also presented them with a low-risk, high-reward opportunity to snag Walker on a discount after he agreed to a buyout with the Oklahoma City Thunder, who had acquired him from the Boston Celtics in a trade back in June, earlier this month.

That paved the way for Walker to sign a two-year, $18 million deal with the Knicks -- the only offer he said he needed to consider once he'd gotten the buyout with Oklahoma City out of the way.

"I think it is," Walker said, when asked if this was the perfect time for him to come back home. "Everything. Perfect timing. Really motivated. Super excited that these guys have belief in me.

"That's all I need. I just need somebody to believe in me. These guys do, and I appreciate that."

That answer -- "I just need somebody to believe in me" -- left a rather obvious question: Did Walker, who signed a four-year max contract with Boston two summers ago, only to be traded, along with a first round pick, for Al Horford back in June in the first significant move of Brad Stevens' tenure as the team's president of basketball operations -- think the Celtics believed in him?

"I definitely felt like Boston believed in me," Walker said, before adding with a smile and a shrug, "but they traded me. But, yeah, that's not the case. I don't feel like they didn't believe in me."

What there is little doubt of is that New York believes in Walker. Representing all Knicks fans Tuesday was rapper Fat Joe -- a fellow Bronx native -- who was wearing a white No. 8 Walker jersey to the press conference. And, afterward, he declared Walker would return to his All-Star form with the Knicks.

"He's the real deal," Joe said. "He's certified out here.

"Kemba is like ... when they talk about NYC being the Mecca of Basketball -- he's that."

The biggest question about Walker at this point is the state of his left knee. Walker has been dealing with issues with it since the start of 2020. He started last season late after undergoing a 12-week strengthening program in the offseason and didn't play in back-to-backs last season.

When asked if that would be the case this season, Walker smiled and said, "You gotta ask him," referring to coach Tom Thibodeau, who was sitting alongside team president Leon Rose and general manager Scott Perry in the front row.

Thibodeau's response was one word -- "Playing" -- which generated a round of laughter.

Fournier also played alongside Walker last season with the Celtics, having been acquired by them at the trade deadline into the trade exception created when Gordon Hayward was dealt to the Charlotte Hornets in a sign-and-trade deal last offseason.

In order to try to do the same thing, the Celtics came to an agreement with the Knicks on another sign-and-trade deal Tuesday, sending two future seconds -- one heavily protected -- to New York to make the deal.

Fournier is coming off a strong showing at the Tokyo Olympics with the French National Team, with whom he won the silver medal, and said Thibodeau gave him a hard time about that during New York's recruiting call with him.

"Yeah, my confidence level was good," Fournier said of playing in Japan. "It's really good, actually. When I was on the phone with Leon, Thibs, Scott, the first thing Thibs told me [before the gold medal game] was "As soon as I wrapped up silver, I had to come to New York so we could talk."

"That was his way of talking a little bit of trash, and unfortunately that's what happened. But I'm proud of what we accomplished for my country, and the goal is to keep shining for France and in three years we host the Olympics in 2024, so we'll see. We'll see."

The same could be said for Walker, and for the Knicks, who are trying to back up their surprising breakthrough season in 2020-21 with another playoff appearance next season, just as Walker is trying to return to his old form.

And while he said he doesn't feel more pressure playing in New York -- though he joked he's already telling people he only gets four tickets per game -- he admitted it has been different knowing he's going to be playing for his hometown team.

"This feeling has been like no other. Just randomly getting goosebumps," he said. "It's an unbelievable feeling to be able to come home. As far as added pressure -- I don't think so. As long as I'm in a great environment around great people I'll be fine."
