The players union is reviewing if the Raiders followed the concussion protocol with quarterback Terrelle Pryor during Monday's loss to Denver.
Pryor suffered a concussion late on a hit by linebacker Wesley Woodyard. He remained in for two plays before leaving.
Pryor defended the team Wednesday.
"Looked like I was functioning. I watched the tape," he said. "I could definitely see why they didn't see it. I was talking to them, so I was fine because they were asking me (questions); definitely a delayed reaction."
A league spokesman said all indications are the Raiders handled the situation properly.
After the game, coach Dennis Allen said Pryor showed no immediate symptoms and the team followed the procedures.
Pryor didn't practice Wednesday. He took a concussion test to determine if he can do so today, but the results weren't available.
"I think it was very mild because I'm doing very well," Pryor said. "They said I'm taking very good steps toward being able to play."
Ex-Buc linebacker's sentenced reduced
CINCINNATI — Former Bucs linebacker Nate Webster must serve only 10 years of his 12-year prison sentence for having sex with the underage daughter of a former Bengals assistant coach.
The Ohio 1st District Court of Appeals ruled prosecutors didn't prove one of four counts for which Webster was convicted last year. Webster, a star at the University of Miami, played for the Bucs from 2000-03. Prosecutors say Webster, who was with the Bengals at the time, had sex with the girl several times in 2009, when she was 15. Webster, 35, said the sex occurred when she was 16, Ohio's age of consent.
