Raiders quarterback Terrelle Pryor played a solid game Monday night against the Broncos despite a loss, but he left the game early—as did cornerback Tracy Porter. We now know why. Pryor and Porter sustained concussions during the 37-21 loss, Vic Tafur of the San Francisco Chronicle reports. Pryor went to the locker room with four minutes remaining in the fourth quarter after he was hit by Danny Trevathan and Wesley Woodward. Matt Flynn played quarterback on the Raiders' final drive. In his fourth-career start, Pryor completed 19 of 28 pass attempts for 281 yards and a touchdown. Source: Sporting News
