The sports star was arrested in September, 2010, after his ex-girlfriend, Josie Harris, accused him of striking her "multiple times in the head with his fist" and allegedly threatening to beat up their two children, who at the time were aged nine and 10.
Last December (11), the athlete struck a plea deal with prosecutors to escape a felony battery charge and pleaded guilty to a lesser count of misdemeanour domestic violence. He also pleaded no contest to two misdemeanour harassment charges.
Las Vegas Justice of the Peace Melissa Saragosa then handed Mayweather, Jr. a three-month jail sentence and ordered him to complete 100 hours of community service, enrol in a 12-month domestic violence programme and pay a $2,500 (GBP1,560) fine.
The boxer was due to begin his term at Sin City's Clark County Detention Center by 6 January (12) but on Friday a judge permitted Mayweather, Jr. to delay the sentence and instead train for a proposed fight with arch-rival Manny Pacquiao on 5 May (12) at the MGM Grand.
As per the judge's ruling, the athlete will now have until 1 June (12) to turn himself in, according to TMZ.com.
Several of the star's celebrity pals were on hand to show their support at the court house - among them singer Ray J and rapper Lil Kim.
If Mayweather, Jr. fails to obey to the terms of the agreement, the boxer will be forced to serve another three months behind bars.
