Penn State coach Joe Paterno kept the selection of his starting quarterback for Saturday's game against Northwestern under wraps until game-time.
And before the first quarter was over, he already had used both quarterbacks.
Freshman Rob Bolden started the game and led the Nittany Lions into Northwestern territory on the team's first two series. On the second series, however, Bolden was hit by Hunter Bates on a blitz as he tried to pass and fumbled, with the Wildcats recovering.
Bolden looked shaken up but walked off the field under his own power. But when the Lions began their next possession, McGloin was at the controls.
There was no immediate word on any injury to Bolden.
