Penn State quarterback Christian Hackenberg has been on a hot streak, but he got off to a slow start Saturday against Northwestern.

He also hit an official in the head with a pass in the first quarter.

Ouch.

That pass was one of nine incompletions among Hackenberg's first 12 pass attempts on the afternoon.
