NFLPA Probing Terrelle Pryor Concussion Case
Pryor suffered a concussion when hit by Broncos linebacker Wesley Woodyard and yet remained in the game for two snaps before leaving with medical staff for the locker room to be evaluated.
"It's questionable,'' a source told ESPN.
The union is awaiting receipt of the official game report from the Raiders before deciding how to proceed.
