MANILA, Philippines – Junior middleweight boxer James Kirkland shared a piece of advice that may help Floyd Mayweather Jr. during his stay in prison.
"They say Floyd's in the gym every day, and that's what's going to keep him alive in there," Kirkland said in RingTV.com.
Mayweather is headed to the Clark County Detention Center in Las Vegas for a 90-day sentence.
He pleaded guilty to domestic battery charges involving his former girlfriend, Josie Harris.
Kirkland knows how hard life is in prison.
He spent time at the Bastrop Federal Prison in Texas after pleading guilty to a charge of gun possession in April of 2009.
"It takes hard, hard work and a lot of dedication to beat those walls and to survive, man. I basically gave myself something to do every day,” he said.
Before being imprisoned, Kirkland was an undefeated boxer and was in line to face Michael Walker for WBO and WBA title shots.
Kirkland said Mayweather can turn prison into a gym.
“You can turn it into, like, a stable training camp, somewhere you can be focused in. He can turn it into a stationary training camp and put all of his cards on the table every day,” he said.
