Titans rookie tackle Taylor Lewan has said repeatedly he was merely breaking up a fight the night he was charged in an incident while in college.

His ex-girlfriend and the alleged victim say otherwise.

Lewan, a first-round pick of the Titans who played at Michigan, is facing three misdemeanor charges — one count of aggravated assault, two counts of assault and battery — stemming from the Dec. 1 incident on campus after the Ohio State-Michigan game.

According to a 36-page Ann Arbor police report obtained Thursday by The Associated Press, James Hughes of Denver said Lewan hit him in the face and Alexandra Dileo, whose brother was a teammate of Lewan's, said "Taylor is lying" about his actions.

"He knocked the guy to the ground and he punched him," she told police in a telephone interview Jan. 29, according to the report. Per the report, she recalled hearing Lewan tell his mother "I knocked a guy out" the next morning while they were having breakfast.

Lewan is scheduled to return to a Michigan court room on June 16 after his pretrial hearing was delayed during a court appearance earlier this month. His attorney, John A. Shea, entered a not guilty plea for Lewan "at my request for further investigation."

Lewan, Hughes, Dileo and others interviewed by police acknowledged they had been drinking alcohol on the night in question. Lewan's motives were "related to the University of Michigan and Ohio State rivalry and to levels of intoxication," according to the report.

Dileo expressed concerns to police that people would feel she was lying because she and Lewan had broken up. But she "stated she knows what happened and Taylor is lying."
