Las Vegas – Boxer Floyd Mayweather was released from a Las Vegas jail early Friday after serving two months of a three-month sentence in a misdemeanor domestic battery case.

The undefeated boxer walked out of the Clark County Detention Center in darkness to resume his boxing career.

Mayweather's lawyers and personal physician said in court documents that jail food and water didn't meet Mayweather's dietary needs, and lack of exercise space in a cramped cell of fewer than 98 square feet threatened his health and fitness.

The 35-year-old boxer pleaded guilty last year to reduced charges stemming from a hair-pulling, arm-twisting attack on his former girlfriend. The plea deal allowed him to avoid trial on felony charges that could have gotten him up to 34 years in prison. – Sapa-AP
