After sitting out the opener against Hawaii because of a foot injury, USC linebacker Morgan Breslin hopes to play Saturday against Washington State.
But Jabari Ruffin showed he can be a capable replacement.
Ruffin, a redshirt freshman from Downey, started Thursday's game and made three tackles in the Trojans' 30-13 victory.
"I tried to know what to expect my first college game," Ruffin said, adding that defensive line coach Ed Orgeron, "got me right in camp. I basically did everything he taught me and played hard."
Breslin also assisted Ruffin from the sideline.
"He was helping out there every series," Ruffin said. "He was telling me things I could do better and things I was doing well. It was really good to have a vet like that in my ear."
