New Southern California coach Lincoln Riley watched the Trojans practice Tuesday, getting a look at his next team following his surprise departure from Oklahoma.

Southern California has hired Oklahoma’s Lincoln Riley to be its next coach in a stunning and rare move of one traditional college football powerhouse swiping the another’s highly accomplished head coach.

Chance Nolan threw four touchdown passes and Oregon State beat Southern California 45-27 on Saturday night. Tyjon Lindsey had five receptions for 102 yards and two touchdowns, B.J. Baylor ran for 158 yards, and the Beavers (3-1, 1-0 Pac-12) ended a 24-game losing streak — dating to 1960 — at the Los Angeles Memorial Coliseum.

The quarterback competition at Southern California might be over before it even started. Jaxson Dart did not practice Tuesday after the freshman sustained a knee injury in the Trojans’ 45-14 win at Washington State, while three-year starter Kedon Slovis took first-team reps after being knocked out of the game because of a neck injury. Interim coach Donte Williams would not discuss the status of Dart, who came off the bench to throw for 391 yards and four touchdowns.

Clay Helton’s players hate the fact their head coach’s firing was a cause for celebration for much of Southern California’s vast football fan base.

Southern California has fired football coach Clay Helton two games into his seventh season in charge.
