ALAMEDA -- Terrelle Pryor was cleared to play Friday under the provisions of the NFL concussion protocol, but he has another hurdle remaining before he can take the field as the Raiders quarterback against the Washington Redskins on Sunday at O.co Coliseum.
Coach Dennis Allen said that although Pryor had made "significant progress," the Raiders would administer one more test Saturday before Allen makes a decision on whether Pryor or Matt Flynn would start.
"It's not something that has to be done," Allen said. "It's something that we want to do to make sure. I want to make sure we're making the right decision for this kid.''
The addition of an extra test came as a surprise to Pryor, but he welcomed the idea.
"That just shows they take care of their players," Pryor said. "I feel great, I feel fine.''
After getting in minimal work the previous day, Pryor got considerably more snaps Friday and was officially listed as "questionable" to face Washington.
"I don't know if it will be a game-time decision or not, but the key is that both (Pryor) and Matt Flynn have prepared this week to start," Allen said. "I'm going to make the right decision based on his health.''
Allen conceded that delaying the decision offered an opportunity for a "competitive advantage" in that Washington has to prepare for two quarterbacks, and in that regard, the story has played out the way Redskins coach Mike Shanahan thought it would.
"You have to get ready to play both of them," Shanahan told Bay Area reporters Wednesday by conference call. "That's their game plan.''
While Allen said the choice will be based on Pryor's health, there is also the matter of minimal practice time for a developing player who has yet to play in an NFL game after being a spectator for the better part of a week.
If Pryor is rusty or a step behind, he could be prone to mistakes or the kind of helmet-to-face-mask hit he received against Denver from Wesley Woodard.
If Pryor is somewhere near approximating full strength, he immediately takes some of the steam out of the Washington outside pass rush led by Brian Orakpo and Ryan Kerrigan, as opponents have taken a more measured rush in order to keep Pryor from breaking outside.
"I feel 100 percent, definitely," Pryor said. "Matt definitely had a lot more reps than me this week. I don't know what it's going to be, but I know I'm going to study these next two days real hard as if I am starting.''
Pryor said he felt sharp mentally after Thursday's practice when he properly identified a check-in system coaches had given him the day before.
"As the days progressed, I kept getting better and better," Pryor said. "It's not something that gets better at the snap of a finger.''
Altought Pryor said "I believe in my ability and always think I'm the best player on the field," he realizes the decision is out of his hands.
"It's up to the boss upstairs, and that's Coach Allen," Pryor said. "He's our leader, and whatever our leader decides is what's going to happen.''
Allen hopes Watson can resume practice on a limited basis next week.
Concussion victims linebacker Sio Moore and cornerback Tracy Porter were full-go in practice and listed as probable, as was fullback Jamize Olawale (ankle). Guard Lucas Nix was questionable, and Andre Gurode is the likely starter on the left side.
