Oakland Raiders quarterback Terrelle Pryor participated in team practice on Friday, according to Steve Corkran of the Contra Costa Times. Pryor was cleared to practice on Thursday and participated in a limited fashion then as well, after missing Wednesday's session.
Pryor has cleared the concussion tests required thus far. He suffered the concussion in Week 3 against the Denver Broncos. There was (is) a lot of controversy surrounding the injury, given that Pryor went back into the game after sustaining a hard hit that caused him to get up slowly.
After the game, Pryor admitted to not remembering the play in which he likely sustained the injury. But the NFL is strict regarding concussion tests and things of that nature, so if him being at practice means he really has been cleared, he could play in Week 4. Corkran's opinion is that Pryor has a solid chance at playing, since the Raiders wouldn't waste meaningful practice snaps on an injured player with no chance to play.
Fantasy Impact: In two-QB leagues, Pryor is a somewhat desirable option. He can pick up rushing yards and seems to have a lot of boom-or-bust potential. However, if you happen to have a player who might be serviceable in his place, then you should sit Pryor at this point. There are mixed reports regarding his status. Matt Flynn would get the start if Pryor can't go.
