Penn State quarterback Drew Allar suffered an apparent knee injury during Saturday's win over Wisconsin that puts his availability for next week's battle against No. 4 Ohio State in question.
Allar was seen walking off the field with a limp in the second quarter.
Allar came out of the tunnel for the second half and practiced throwing on the sideline, but did not return to the game. Backup quarterback Beau Pribula finished out the win in his stead.
Allar could be seen celebrating with his teammates after the game.
