The footage from just after halftime of Penn State's game against Wisconsin last Saturday night captured quarterback Drew Allar throwing a pass and then shaking his head. Allar, who exited during the second quarter, reappeared from the locker room wearing a brace on his left knee but never seemed comfortable during an accelerated warmup before the second-half kickoff. He threw a pass, turned to a member of the Nittany Lions' coaching staff and shook his head in frustration. No matter how many times Allar flexed his knee on the sideline, desperately attempting to work out the kinks, the discomfort refused to subside.
