LAS VEGAS (AP) — Floyd Mayweather Jr. has turned himself in to begin serving a three-month sentence in a Las Vegas jail for attacking his ex-girlfriend in September 2010 while two of their children watched.

The undefeated five-division champion surrendered Friday before Justice of the Peace Melissa Saragosa, who allowed him to remain free long enough to headline a May 5 fight.

Mayweather said nothing in the brief appearance before he was handcuffed and taken out of the courtroom. Saragosa praised the champ for complying with the court orders up to this point. Mayweather has done portions of his community service and counseling and will next be in court for a  status check in November.

Las Vegas police say that as a high-profile inmate, the 35-year-old Mayweather probably will serve most of his time away from other prisoners in a small solo cell.
