Floyd Mayweather starts jail sentence today (June 1) at Clark County Detention Center

Boxing champion Floyd Mayweather Jr. could have gotten 34 years in prison after getting slapped with domestic violence charges stemming from a 2010 incident involving the mother of three of his kids.

Starting today (June 1, 2012) he'll serve just 87 days.

That's because "Money" plead guilty to misdemeanor domestic battery and no contest to two harassment charges, prompting prosecutors to drop felony charges prior to his sentencing back on Dec. 22, 2011. Mayweather remained free as part of a plea deal that allowed him to fight Miguel Cotto last month in "Sin City."

Time's up.

The undefeated pugilist must now surrender to Las Vegas Justice of the Peace Melissa Saragosa, who will then make arrangements to have him transported to the Clark County Detention Center for detainment.

The Associated Press has a description of Mayweather's new pad after the jump.

Mayweather will be housed in a standard administrative segregation cell no larger than 7-by-12 feet, with a bunk, stainless steel toilet and sink, a steel and wood desk with a permanently bolted stool and two small vertical windows with opaque safety glass.

Mayweather could have about an hour a day out of his cell with access to an exercise yard. Depending on his behavior, the boxer could later get several hours a day for exercise with other inmates also being held in protective custody.

He'll get a standard-issue blue jail jumpsuit with the letters CCDC and orange slippers.

Mayweather will be able to deposit money into a jail account to purchase snacks, soap and personal hygiene items from the jail commissary.

Sounds like fun.

In addition to 90 days in jail (with credit for three days served), Mayweather must also pay a $2500 fine, which is sure to break the bank, considering he made $32 million for beating up Cotto. He's also saddled with 100 hours of community service and will be required to enroll in domestic violence counseling.
