Oakland Raiders quarterback Terrelle Pryor was ruled out for Sunday's game after experiencing concussion symptoms on Saturday night, according to a report.
After Pryor showed "the slightest sign of a concussion," Raiders players were informed that backup Matt Flynn would start against the Washington Redskins, FoxSports.com reported.
Pryor was cleared to practice on Thursday, just three days after suffering a concussion late in Monday night's loss to the Broncos. He beat out Flynn for the No. 1 quarterback position during the preseason.
