World champion boxer Floyd Mayweather Jr. reports to the Clark County Detention Center in Las Vegas today to begin his sentence for pleading guilty to a reduced domestic battery charge last December, reports USA Today's Bob Velin.
Mayweather's sentence is for 87 days, but he could serve less with good behavior. For at least the first week, he will be in isolation. Mayweather will remain in his cell for about 23 hours a day.
The domestic battery charges came as a result of an incident in September 2010 with Josie Harris, the mother of three of his children.
Mayweather was initially scheduled to start his sentence in January, but his lawyers sought to push the sentence back until June 1 to allow Mayweather time to get in another fight.
On May 5, Mayweather defeated Miguel Cotto in Las Vegas. Mayweather, always the showman, walked in with a posse that included teenage pop star Justin Bieber. The fight was tightly contested, though, as Mayweather and Cotto exchanged blows. Mayweather was just a little bit better, though, and won by unanimous decision.
