Authorities say a Rochester man bit off part of his brother's ear after they began fighting during a Super Bowl party.

The Democrat and Chronicle of Rochester reports (http://on.rocne.ws/1n7nAn3 ) that police say 27-year-old Sean Fallon-Nebbia was hosting the party Sunday at his apartment.

A roommate told police the brothers had been drinking before they started roughhousing after the game, and the tussle turned violent. Police say Fallon-Nebbia bit off part of 26-year-old Frank Fallon-Nebbia's right ear and punched him several times in the face, knocking him out.

The younger brother was treated at a Rochester hospital.

The older brother is being held in Monroe County Jail on $15,000 bail after pleading not guilty Monday to first-degree assault, a felony. It couldn't immediately be determined if he has a lawyer.
