“I go ‘Do you have any gear’? He goes, ‘What gear do I need’? I tell him, ‘Get one of those headgears’. He says ‘Why do I have to wear a helmet? Nobody else is wearing a helmet’.
“He’s sparring with this guy named Vinnie Lopez. He gets hit by an uppercut while he’s hitting Vinnie with an overhand’.
“He turns around and I go, ‘Oh s—, he’s hurt’. I go to him and I’m like, ‘Are you good’? He goes, ‘That felt so f—– good’. He’s looking at his fist.
