Irish sophomore receiver Michael Floyd received a citation for underage drinking after his involvement in a fight in Minneapolis on Jan. 8, according to police reports and the Chicago Tribune.
The Tribune reported that Floyd was involved in a "physical altercation" outside of a party. University of Minnesota police said Floyd admitted to doing "a couple of shots" earlier in the night and had blood on his hands, feet and shirt.
The police were responding to a report of about 10 people involved in a "physical dispute in the street."
Floyd was cited for underage consumption of liquor, a misdemeanor, the Tribune reported, and could face a fine, court appearance or a diversion program.
Floyd missed five complete games last season after suffering a broken collarbone against Michigan State, but he still recorded 44 receptions for 795 yards and nine touchdowns in seven games last season.
Notre Dame officials, including newly-hired Irish coach Brian Kelly, have yet to comment on the situation.
