USC's already-diminished roster has taken another hit as outside linebacker Morgan Breslin will be out for the rest of the regular season with a hip injury.
"Breslin will have surgery within a couple of weeks," interim coach Ed Orgeron said Wednesday. "He will be out for an extensive period of time, but he could get back later."
The Trojans' hope is that the 6-foot-2, 250-pound senior will recover in time to play in a bowl game.
Breslin has been on the sidelines for most of this season, but led the Trojans (6-3, 3-2) with 13.5 sacks and 19.5 tackles for a loss in the 2012 season.
"In 27 years of coaching, Breslin is one of my favorite players," Orgeron said. "He is totally dedicated to football and has a unique sense of humor."
Breslin missed games against Hawaii, Arizona, Utah and Oregon State due to hip and ankle injuries, but in the five games he played this season he recorded 4.5 sacks and eight tackles for a loss.
"He's a terrific player," Orgeron said. "He just plays so hard."
J.R. Tavai has stepped up in Breslin's place, and totaled 10 tackles and 3.5 tackles for a loss in the game against Arizona.
