Penn State QB Drew Allar did not start in the second half against Wisconsin due to an apparent injury

MADISON, Wis. (AP) — Penn State quarterback Drew Allar left Saturday's game against Wisconsin late in the first half and went to the locker room with a trainer. Allar looked banged up after taking a sack on the final possession of the first half with Penn State trailing 10-7.

As he left the field, he grabbed his left knee. As Allar jogged out of the tunnel after halftime — and did so gingerly before attempting a few throws — backup quarterback Beau Pribula led the offense on the first drive of the second half. While Pribula entered the field, Allar stood on the sideline with a towel over his head and a brace on his left knee. Within minutes, he took the brace off but remained on the sideline next to quarterbacks coach Danny O'Brien.

Pribula, a more mobile quarterback than Allar, has used his legs this season. Penn State's No. 3 quarterback is freshman Ethan Grunkemeyer. Allar was sharp in the first quarter, completing 9 of 10 passes for 113 yards. His only incompletion was a drop from Julian Fleming. Allar went 14 of 18 for 148 yards in the first half with a touchdown pass to running back Nick Singleton.

Allar's availability for next week's game against No. 4 Ohio State at Beaver Stadium now comes into focus.
