DENVER -- Raiders quarterback Terrelle Pryor suffered a concussion on a helmet-to-helmet hit by Broncos linebacker Wesley Woodyard late in Oakland's 37-21 loss to Denver on Monday night.
The injury puts Pryor's status in doubt for Sunday's home game against winless Washington.
Per NFL policy, the concussed Pryor was not made available to speak to the media following the game, although he was at his locker and did not appear to be disoriented as he dressed. He has to go through the league-mandated concussion protocol to be cleared this week.
However, Pryor used his Twitter account to share his thoughts Tuesday morning.
Sorry about the loss RaiderNation. I don't remember much ! Good hit by whoever it was. I heard our team fought well .. We will be back!

Pryor was hit on a second-and-goal play from the Broncos' 6-yard line with about 6:30 to play when a blitzing Woodyard came through unimpeded to stop him for a 2-yard loss. Pryor stayed down face-first on the grass for a bit but remained in the game for two more plays, even though he seemed stunned during a stoppage in play to determine whether he had fumbled.
After the Raiders lost possession on downs -- Pryor hit Rod Streater for a 7-yard gain to the 1-yard line before Denarius Moore failed to haul in Pryor's bullet in the end zone -- Pryor walked to the locker room and was replaced by Matt Flynn for the team's final series.
Asked whether the hit looked like an illegal helmet-to-helmet blow, Raiders coach Dennis Allen said he could not tell.
"Within the rules, it's inside the tackle box," Allen said. "But it was a pretty good hit."
Allen was then asked whether Pryor would be available against Washington.
"I have no idea," Allen said. "He's got to go through the protocol, just like everybody else.
"He took a shot on that particular play, but I think that play could have happened to just about anybody."
Pryor finished with a quarterback rating of 112.4 in completing 19 of 28 passes for 281 yards with a 73-yard touchdown pass to Moore. He also ran for 36 yards on four rushes but was sacked three times for 23 yards.
For the second consecutive game, Pryor did not commit a turnover.
"It's a guy that's getting his chance, and with each week, he's getting a little bit more comfortable," Raiders safety Charles Woodson said. "He did some good things tonight, so it would be a tough blow [to lose him], especially for him and his development as a player if he's not able to shake it off and bounce back and come back next week. We'll just see how that pans out."
Pryor wasn't the only Raider to be injured Monday night, as cornerback Tracy Porter also was diagnosed with a concussion.
