USC head coach Clay Helton announced after Sunday's rainy practice that senior outside linebacker Jabari Ruffin had been suspended indefinitely from all team activities for a "student conduct" issue.

"I don't have a Crystal Ball for if or when he could return," said Helton.

The backup OLB has just 2 total tackles on the season.

This is the second time Ruffin has been suspended this season, suspended half a game for stomping on an Alabama player in the season opener.

Ruffin also missed time with a concussion.

Helton declined to give further details on the student conduct issue.
