Ohio State wide receiver Austin Mack could be out for the rest of the season after undergoing surgery on his left foot.
Mack injured his foot in the 49-20 loss at Purdue and will be out indefinitely.
The average length of recovery from this type of injury is six-to-eight weeks.
Head coach Urban Meyer says Mack might be back for their bowl game.
Mack has caught 26 passes for 331 yards and a touchdown.
