There has been an update on Clifford's status in the third quarter of the game.

Sean Clifford has endured many injuries while serving as Penn State's starting quarterback.

He picked up another Thursday night. Clifford came out for the second half against Purdue.

On Purdue's first possession, he jogged back to the locker room with the trainers. 

A touchdown by the Boilermakers led freshman quarterback Drew Allar to the field.

Clifford hurt his left knee in the second quarter. After grabbing his knee, play continued.

Before the first half ended, Clifford played another series. It's clear he has a problem.

As soon as his absence is made public, we'll have the latest information.
