Notre Dame athletic director Jack Swarbrick said quarterback Jimmy Clausen was the "victim of a sucker punch" during the taping of his radio show for WLS Radio 890 in Chicago, according to The Associated Press.
Clausen reportedly has a black eye stemming from an altercation outside a South Bend bar about 2 a.m. Sunday.
After it was originally reported that Clausen pushed a man before he was hit, an unnamed source told the AP that Clausen and his girlfriend were followed outside the bar after the two went back to retrieve her purse.
The source told the AP that Clausen did not fight back.
"He was not engaged in a fight. He didn't throw any punches. He didn't directly engage the individual," Swarbrick said on his radio show that normally airs Saturday. "He just got coldcocked by somebody, and we're very disturbed by that."
South Bend Police Capt. Phil Trent told the AP that the police were called to the scene after receiving report of a fight. He said everyone was gone when the police arrived.
Swarbrick also said on his radio show that coach Charlie Weis would return to South Bend after Saturday's game against Stanford to discuss the coach's future with the program.
Weis had planned to remain in California to recruit after the game like he did last year after a loss to USC.
Swarbrick tried to downplay Weis returning after the game, telling the Chicago Tribune that it was not a sign that Weis was out as head coach. Swarbrick said told the paper it would be easier for the two to set a meeting in South Bend than reconnecting in California.
