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 the judge who sentenced him in December — and then 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.

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.
