LSU on Monday suspended offensive guard Josh Boutte one game for a flagrant personal in the waning moments of Saturday's loss to Wisconsin.
Boutte will miss the Tigers' home opener against Jacksonville State on Saturday.
Boutte, a senior, was thrown out of the game after he leveled Wisconsin defensive back D'Cota Dixon, who had intercepted a pass to ice the Badgers' 16-14 upset of No 5 LSU.
LSU coach Les Miles said that Boutte called Dixon on Monday morning and apologized.
"Josh made a mistake and will serve a one game suspension because of it," Miles told reporters. "Even though this was done by mistake, a play like this does not belong in the game of football and therefore action must be taken.
"This play does not define Josh as a person and is not indicative of the type of player he is. We sincerely apologize for his mistake."
Dixon told the Orlando Sentinel there were no hard feelings.
"I don't blame the kid. He probably was frustrated," Dixon said. "If I was ranked No. 5 and we lost to an unranked team and we were supposed to go to the national championship, I'd be upset too. It is what it is. It's part of the game. No hard feelings."
