ALAMEDA, Calif. (AP) - Terrelle Pryor returned to the practice field for the Oakland Raiders three days after sustaining a concussion but is not participating in team drills.
Pryor was in uniform Thursday and took part in stretching but did not have a helmet and mostly watched backup quarterbacks Matt Flynn and Matt McGloin run practice during the portion open to the media.
Pryor was knocked out of Monday night's loss in Denver in the fourth quarter and did not practice Wednesday. Pryor has said it would be difficult to start Sunday's game against Washington if he did not practice Thursday.
