Defensive end Cassius Marsh apologized Wednesday for swinging at a Cal player this past weekend and getting himself ejected at the Rose Bowl.

The senior committed back-to-back offsides penalties in the second quarter, then reacted when the Bears’ lineman swung at him. UCLA won 37-10, but his three penalties helped set up the Bears’ lone touchdown. Though he was clearly baited, Marsh downplayed that as a mitigating factor.

“It was my fault,” he said. “It was my mistake for reacting. There’s no excuse for my actions. I let down my team, I affected my team, I hurt my team. That’s never OK. I felt horrible about it. It’s a hard thing for me. I’m sure you guys know, it’s been something I’ve been working on my whole career. I will continue to do so.

“It’s hard because I feel like at this point, I have little to no credibility in saying that I will continue to work. But that’s all I can do, is continue to work to control myself, to stay within my game. But like I said before, there’s no excuse. I made the mistake of reacting, and that was my fault, 100 percent.”

Defensive line coach Angus McClure said after Saturday’s game that he was disappointed and a little surprised to see Marsh lash out. The senior had worked to keep his temper under control over the past year, and even tried to diffuse a scrum during a heated spring practice.
