Tight end Jared Cook and the Los Angeles Chargers have agreed to a one-year contract worth a maximum of $6 million, a source tells ESPN's Adam Schefter.

Cook will help fill a void left when Hunter Henry left the Chargers to sign with the New England Patriots.

A 12-year veteran, Cook, who will be 34 when the 2021 season begins, has been playing some of his best football over the past three seasons -- primarily as a pass catcher and matchup issue for opposing defenses.

The 6-foot-5, 254-pounder made his first Pro Bowl with the Raiders in 2018 after setting career highs with 68 catches, 896 yards and 6 touchdowns. Then he went back to the Pro Bowl with the New Orleans Saints in 2019 after catching 43 passes for 705 yards and a career-high 9 TDs.

Cook's production dropped off a bit in 2020, with 37 catches for 504 yards and 7 touchdowns in the regular season, followed by a costly fumble in New Orleans' playoff loss to the Tampa Bay Buccaneers.

Originally a third-round pick by the Titans out of South Carolina in 2009, Cook has also played for the Rams and Packers during his career and has a total of 505 catches for 6,673 yards and 41 touchdowns.
