Oakland Raiders quarterback Terrelle Pryor did not participate in team practice on Wednesday.
The 24-year-old suffered a sprained MCL in his right knee during last Sunday's 24-20 loss to the New York Giants, leaving his place in the team for week 11 in doubt.
CSN California reported via Twitter: "Pryor is out of practice today. Not wearing helmet, not involved in drills. #Raiders."
If Pryor is declared inactive, Matt McGloin will take the starting role for the Raiders when they face the Houston Texans on Sunday.
