Floyd Mayweather Jr. may be one of the richest prizefighters ever.
But the unbeaten five-division champion who goes by the nickname ''Money'' is about to trade life in a posh five-bedroom Las Vegas home for almost three months in a cell about one-third the size of a small boxing ring.
Mayweather is scheduled to surrender Friday before a Las Vegas judge who sentenced him for his guilty plea to reduced domestic battery charges in a hair-pulling, arm-twisting attack in September 2010 on the mother of three of his children.
Mayweather's legal and ring advisers didn't respond to messages Thursday about his scheduled Friday morning surrender before Las Vegas Justice of the Peace Melissa Saragosa.
As a high-profile inmate, police say Mayweather, 35, probably will serve most of his time in a small solo cell. There is floor space for sit-ups and push-ups. But Mayweather's stint in the high-rise Clark County Detention Center is expected to limit his ability to train for another fight.
