Gilbert Melendez is a longtime friend and training partner of Diaz, who says the fighter is retired.
Nick has yet to publicly announce his retirement, but if he is indeed finished fighting, it would leave the fighter’s professional MMA record at 26-9-0-2NC.
“He’s training hard,” said Melendez. “His brand is huge. He’s so dang famous; the guy’s an A-lister now. Everyone knows him where I go. He’s big in the cannabis game out there and hanging out with celebrities, doing appearances. Being a real businessman out there. He has his specialties, and he’s doing good. He’s training all the time, living a good lifestyle.”
