Floyd Mayweather*Now that championship boxer Floyd Mayweather is locked up, his career is looking a bit battered and bruised.

It’s only been 12 days since his life behind bars began, but he’s already worried he won’t be able to bounce back from this part of his life to save his career.

Mayweather states in new legal documents that he thinks his 3-month sentence could have a detrimental effect on his life as a boxer. He’s asking the judge to allow him to serve his time on house arrest instead.

According to the documents, he spends 23 hours a day in isolation for his own safety. But he says the lock up is taking a toll on his body and he’s unable to train at a competitive level.

His doctor even expressed concern about his withering appearance and inappropriate diet. The doc says it could cause “irreversible damage to Mr. Mayweather’s physique.”

The boxer believes that he only has about two years left in his boxing career so every minute lost is a minute lost in the ring.

He’s currently serving time for beating his child’s mother.
