USC linebacker Desman Stephens II was ejected during Saturday's game after delivering a helmet-to-head targeting hit on Oregon quarterback Dante Moore, forcing him off the field on a stretcher.
The play occurred in the second quarter when Moore scrambled for an 11-yard gain and slid near the 12-yard line, with subsequent reports noting Moore suffered a serious collision that snapped his head.
Stephens faced widespread criticism from analysts and coaches after appearing to celebrate and smile on the sideline while Moore received medical attention and was transported to Los Angeles General Hospital.
