Nick Saban looked rough. When he took the podium for his Wednesday press conference after practice, the Alabama football coach’s right eye looked completely bloodshot.

During his appearance on the Pat McAfee Show Thursday, Saban said he didn’t know what had happened. He addressed the eye problem again during his weekly radio show later on Thursday.

“It looks like I’ve been in a gang fight and my gang didn’t show,” Saban joked to host Eli Gold and media guest Brad Nessler.

Saban said the eye didn’t hurt, but after practice Thursday, he had a chat with Alabama’s team doctor, who asked if he had been coughing. Saban said he hadn’t been.

Then, the doctor gave a hypothesis that made sense to the coach.

“He said, ‘You know you can get this from yelling,’” Saban said. “…He said, ‘You got it from yelling, there’s nothing wrong with you, you just got it from yelling. You busted a blood vessel in your eye from yelling too much.’”

Saban and his staff have been trying to prepare Alabama for its Saturday matchup with LSU at Bryant-Denny Stadium. The game will have massive repercussions in the race for the SEC West title, and gives Alabama a chance to avenge its loss in Baton Rouge last season.

The game is scheduled for 6:45 p.m. Saturday. It will be aired on CBS.
