Several college football rivalries boiled over on Hilton Head Island last weekend, leading to fights in a sports bar and in the back seat of a cab being shared by strangers.

The first incident reported to authorities occurred inside Callahan's Sports Bar & Grill, 49 New Orleans Road, during the Michigan-Ohio State game.

A 44-year-old Michigan State University fan, who was cheering against Michigan, reportedly kept using profane language, which angered a 47-year-old Michigan fan who was watching the game with his family, according to a Beaufort County sheriff's report released Monday.

The Michigan State fan kept yelling foul language at "the top of his lungs" after the Michigan fan asked him not to, witnesses told deputies. The Michigan fan pushed the Michigan State fan and briefly put his hands on the 44-year-old's neck, the report said.

The Michigan State fan did not press charges but was arrested for shouting profanities from the back seat of a patrol vehicle after being asked to stop, the report said.

He was checked for injuries at Hilton Head Hospital and taken to the county jail, where he was booked on a public disorderly conduct charge.

The second incident was more of a drunken, philosophical debate over which of two colleges that haven't played each other is the better team.

A 25-year-old Penn State fan said he was slapped in the face several times by a "big guy" who claimed Georgia is better.

The two strangers were sharing a taxi on Palmetto Bay Road at 2:45 a.m. Sunday, according to the report.
