Penn State quarterback Christian Hackenberg barely completed 50 percent of his passes and threw one pick during the Nittany Lions' 23-21 loss to Northwestern Saturday. While he might like a do-over on a few of those incompletions and the interception, one referee probably really wishes one of those passes had gone in a different direction. On Hackenberg's first throw of the day, he drilled a ref directly in the head, knocking him to the ground. Watch a video of the pass via FOX Sports here:
Ouch.
