Undefeated boxing champion Floyd Mayweather Jr. may have to call his boxing career quits by force if he is not released from the Las Vegas jail. Mayweather was put in jail earlier this month for attacking his ex-girlfriend in September 2010. He still has three months left in his sentence.

According to the Las Vegas Review Journal, lawyer Richard Wright filed an emergency motion Monday where he asked if Mayweather could serve the rest of his sentence under house arrest.

"Medical opinion shows that CCDC administrative segregation threatens to end or shorten Mr. Mayweather's boxing career," the motion stated.

Wright says that because Mayweather is not given the opportunity to work out or train in jail, his health is fading. Mayweather is however being kept separate from other inmates due to his celebrity status.

According to the motion, Mayweather's doctor, Dr. Robert Voy, claims that being confined to a jail cell without training could damage his body structure. 

The motion says, Dr. Voy "expressed deep concern for Mayweather's health and explained that any lengthy period of time with an inappropriate diet, coupled with lack of regular exercise, will most likely lead to irreversible damage to Mr. Mayweather's physique."

Mayweather is said to supposedly have eaten less than 800 calories daily since he's been jailed, which is significantly less than the 4,000 calories he takes in during his normal training routine. Additionally, Mayweather is prohibited from using the jail training areas due to his isolation from other inmates, and he is said to not have the space to exercise in his cell. 

The motion additionally states that "Such damage could and, most likely, would lead to Mr. Mayweather being unable to continue his boxing career."
