Oakland Raiders quarterback Terrelle Pryor missed practice on Friday because of a knee injury and is listed as questionable for Sunday's game against the Houston Texans.
Raiders coach Dennis Allen said Pryor had a setback and that his knee felt worse on Friday after sharing reps with rookie Matt McGloin in Thursday's practice.
It appears likely that McGloin will be the starter on Sunday.
McGloin's only game experience in his career came two weeks ago when he completed 7 of 15 passes for 87 yards in garbage time against the Philadelphia Eagles.
Allen still hopes Pryor can play.
"You never know," Allen said of Pryor's status. "He may feel great tomorrow ... we're still preparing him."
