The Nittany Lions will now be without another key starter for the rest of its game against No. 3 Iowa.

Defensive lineman PJ Mustipher has been ruled out for the game after he was seen on the sidelines with crutches. He needed help getting to the tunnel right before halftime after he was injured on a play.

This is a gigantic loss for the Nittany Lions as he had been one of their best player on defense coming into this game. Through 5 games, Mustipher had 21 total tackles (16 solo) with 1 sack.

He was on pace to equal or even surpass his numbers from the last 2 seasons when he finished with 35 and 37 total tackles respectively.

Mustipher is the 2nd major injury that Penn State has had to deal with for this game. In the 1st half, quarterback Sean Clifford got injured and didn’t return to the game out of halftime as all of his playing gear was off.
