Four more members of the Detroit Pistons -- center Isaiah Stewart, point guard Saben Lee, point guard Killian Hayes and shooting guard Rodney McGruder -- entered the NBA's COVID-19 protocols on Thursday, sources told ESPN's Adrian Wojnarowski.

That gives the Pistons five players in the health and safety protocols, including rookie point guard Cade Cunningham, the top pick in the 2021 NBA draft, who entered the protocols on Tuesday.

The Pistons were still set to play the Heat on Thursday night in Miami, sources said.
