At a sparring session ahead of what he says will be his final professional fight against Andre Berto, the undefeated veteran paused and asked one of his posse to retrieve a wad of cash from his bag.
"I gotta look in my bag, please show me what inspires me," he said in a video posted on Twitter by Showtime Sports.
"I need motivation, let me hold it while I train. I've gotta hold it while I work."
He then proceeded to pound the heavy back with his left hand whilst clutching the large sum in his right, much to the delight of his entourage.
