Nick Diaz has left a Mexican rehab facility and is back in the gym, but the fight over who really speaks for him has only intensified.
Recent footage shows Diaz training at Extreme Couture in Las Vegas with longtime teammate Jake Shields, signalling his first sustained return to structured work since a troubled stretch that included a viral “grassu2011burning” clip and the collapse of a planned comeback against Vicente Luque at UFC 310. Reports through 2025 had Diaz in a rehab centre in Mexico for alleged substance issues, with coaches stressing he was safe and in treatment.
