No. 14 Penn State's defense bottled up Jimmy Clausen, the Irish freshman quarterback making his first start, Derrick Williams returned a punt 78 yards for a touchdown and Austin Scott ran for two second-half scores in a 31-10 win at raucous Beaver Stadium.
Clausen finished 17-of-32 for 144 yards and an interception while Nittany Lions quarterback, Anthony Morrelli threw for 131 yards and a touchdown, though Penn State's offense looked shaky much of the day.
Happy Valley rejoiced after the Nittany Lions got payback for Notre Dame's
41-17 win last year in South Bend, Ind.
The Irish are 0-2 for the first time since 2001, when Notre Dame lost its first three games.
