4th-quarter spurt lifts Penn St. over Northwestern

Penn State's defense clamped down after Northwestern lost starting quarterback Mike Kafka.

In the fourth quarter, the Nittany Lions' offense kicked in.

Evan Royster bolted 69 yards for a TD to cap a three-score spurt in the final period and No. 12 Penn State pulled away to a 34-13 victory Saturday night.

"You got to understand that a kid like that quarterback (Kafka) is out of there, it's a big loss," Penn State coach Joe Paterno said. "Kafka's a heck of a football player. We played them more aggressively in the second half and did a better job with the pass rush, regardless of whether Kafka was in there or some other kid."
