Raiders head into short week with uncertainty at quarterback after Terrelle Pryor's concussion

The Oakland Raiders will begin a short week of preparation with uncertainty about who will start at quarterback as Terrelle Pryor recovers from a concussion.

Pryor was knocked out of Monday night's 37-21 loss at Denver in the fourth quarter after a hard hit to the helmet by Wesley Woodyard and was replaced by Matt Flynn.

Pryor will not be able to practice until he goes through the league-mandated concussion protocol. That means the Raiders (1-2) will have to prepare for Sunday's game against Washington (0-3) with the possibility that either Pryor or Flynn could start.

Coach Dennis Allen said he will have a better idea on Wednesday about Pryor's status but that no final determination will be made until later this week.
