Redshirt freshman quarterback Everett Golson, who led Notre Dame to an undefeated regular season in 2012, and then to the BCS title game against Alabama, is no longer enrolled at the university.
Rumors on social media outlets began to swirl late Saturday and the university confirmed Golson was no longer at the school.
"Everett is not enrolled at the university. Federal law and our own polices preclude us from discussing specifics," school spokesman Dennis Brown told South Bend (Ind.) television station WNDU-TV.
The Chicago Tribune, citing two sources said Golson was not in school because of "an academic violation."
Brown would not indicate when coach Brian Kelly might have a statement or whether Golson could return to school, according to USA Today. However, he is not expected to be available to the Irish during the 2013 season.
USA Today also reported that Golson finished the spring academic semester at Notre Dame.
Golson started 11 games for the Fighting Irish last season, completing 58.8 percent of his passes. He threw for 2,405 yards and 12 touchdowns, along with six interceptions. A dual-threat, Golson as a freshman joined Theismann (1970) and Jarious Jackson (1999) as the only quarterbacks in program history to throw for more than 2,000 yards and rush for more than 300 in a season.
The Fighting Irish have three quarterbacks on their roster. With 18 starts, senior Tommy Rees has the most experience. Rees, who played in all 12 games last season, has thrown for more than 4,400 yards and 34 touchdowns during his Irish career.
Fourth-year junior Andrew Hendrix and Malik Zaire, a spring enrollee who was the No. 6 quarterback prospect in the nation according to ESPN ratings, are also on the roster.
Zaire was considered a recruiting coup for Kelly, but at 6-1 and just 196 pounds is expected to need some time in the program before being ready to see game action.
Earlier this spring, Gunner Kiel transferred to Cincinnati.
