LOS ANGELES -- A jubilant and sizable contingent of visiting Penn State fans weren't leaving until Tyler Warren did first.

In the extra period, Abdul Carter and Dani Dennis-Sutton — Penn State’s projected first-round pick defensive ends — did their thing. Dennis-Sutton had a second-down TFL, Carter pressured Moss into a third-down incompletion, and USC kicker Michael Lantz missed from 45 yards.

Warren had 17 catches, Ryan Barker hit a 36-yard field goal in overtime, and the Nittany Lions erased a 14-point second-half deficit to stun the Trojans.
