Florida State said Wednesday that quarterback Jameis Winston, last season’s Heisman Trophy winner, would be suspended for the first half of the top-ranked Seminoles’ home game Saturday against No. 22 Clemson after he shouted an obscene statement in the student union Tuesday.

“As a result of his comments yesterday, which were offensive and vulgar, Jameis Winston will undergo internal discipline and will be withheld from competition for the first half of the Clemson game,” Florida State’s interim president, Garnett S. Stokes, and Athletic Director Stan Wilcox said in a joint statement. The university declined to comment further.

At a news conference Wednesday, just after the suspension was issued, Winston said he wanted to apologize “to the university, to my coaches and to my teammates” and called his behavior “selfish.”
