ALAMEDA — It's looking more and more as though Oakland Raiders quarterback Terrelle Pryor's sprained right knee will keep him out of Sunday's game in Houston.
A day after appearing to make progress on the practice field, Pryor suffered a setback on Friday and is listed as questionable.
“He wasn't as good today as he was yesterday,” Raiders coach Dennis Allen said. “But you never know. We'll take a look at him. He may come in tomorrow and be ready to go, so we'll see.”
Undrafted rookie Matt McGloin, the only other quarterback on the Raiders' 53-man roster, worked exclusively with the first-team offense and will start if Pryor is unavailable.
Pryor, who leads all NFL quarterbacks with 504 yards rushing, initially injured his knee in the second half of Oakland's 49-20 loss to the Philadelphia Eagles on Nov. 3.
He convinced the coaching staff to let him play the following week against New York and wore a thick brace over his knee, though his mobility was clearly not the same. The Giants held Pryor to a season-low 19 yards on the ground and registered four sacks while sending the Raiders to their third loss in four games.
Pryor was held out of practice Wednesday initially as a precaution. He returned Thursday, albeit in a limited fashion, then was downgraded 24 hours later.
If McGloin starts, it would cap a meteoric rise after the former Penn State quarterback began training camp fourth on the depth chart. He steadily climbed the ranks, however, and moved into the backup role after the Raiders released Matt Flynn on Oct. 7.
McGloin made his NFL debut midway through the fourth quarter against the Eagles and completed 7 of 15 pass attempts for 87 yards.
