ALAMEDA -- A request by Terrelle Pryor to wear a shaded visor in his helmet was a tipoff to coach Dennis Allen that perhaps the quarterback wasn't ready to return from a concussion.

Pryor instead watched from the sideline wearing sun glasses Sunday as the Raiders fell to the Washington Redskins 24-14 with Matt Flynn at quarterback.

``Sensitivity to light is obviously a symptom and when you have that symptom we can't put him at risk,'' Allen said Monday at his weekly press briefing.

Allen said Pryor will continue to be monitored and will not play until he's ``symptom free.'' He is hopeful Pryor will be able to face the San Diego Chargers in Week 5.

Pryor, Allen said, wanted to play against Washington.

``This was not a play decision. This was not a coach's decision. This was a medical decision,'' Allen said. ``There were still some symptoms there, but we weren't going to put him in that situation. That's the right thing to do and that's the decision we made.''

Pryor has already has passed the protocol mandated by the NFL and was technically cleared to play against Washington.

``Part of the tests are objective and some of them are subjective,'' Allen said. ``We probably went a little bit above and beyond what the protocol would be. We just deemed it wasn't worth the risk.''

Responding to media accounts which were highly critical of Flynn's play, Allen said, ``I want to make one thing perfectly clear. This game of football is not about one person. It's about 11 guys on each side of the ball. It's about offense, it's about defense, it's about special teams. At no point was this ever made about one guy.''
