ALAMEDA, Calif. (AP) - 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.
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, wore a thick brace over his knee during last week's loss to the New York Giants when he was held to a season-low 19 yards on the ground and sacked four times.
McGloin could start after entering training camp fourth on the depth chart.
