Nick Diaz returns to training after health issues, botched UFC comeback concerned loyal fanbase

UFC legend Nick Diaz is back in the gym after multiple failed comeback attempts in 2024 and growing concerns about his well-being.

Former UFC title challenger and superstar fighter Nick Diaz looks to be in great spirits after a tumultuous last few years away from the Octagon.

Diaz, 42, was scheduled to make a UFC comeback attempt against Vicente Luque in August 2024 at UFC Abu Dhabi, but the bout was postponed due to travel issues on Diaz’s side. The fight was then rescheduled for UFC 310, but Diaz withdrew from the fight due to undisclosed reasons and was subsequently replaced by Themba Gorimbo.

Since UFC 310, Diaz was seen in viral footage displaying concerning behavior, including attempting to light a piece of grass on fire in a video clip. Several of Diaz’s longtime friends and teammates provided subtle updates on Diaz’s health after the footage went viral, assuring fans that Diaz is getting help and assistance for undisclosed issues.

Nearly a full year after the clip concerned loyal fans online, Diaz appears in great spirits and has returned to the gym.

“A little play sparring with Nick Diaz this morning,” Shields posted of Diaz.

“Nick was my top sparring partner for over 15 years, so it’s good to get back together and train.”

As of this writing, it’s uncertain whether or not the 42-year-old Diaz still wants to compete in combat sports. His last fight came against former UFC welterweight champion Robbie Lawler at UFC 266, losing by TKO.

Diaz is regarded as one of the most beloved fighters to ever compete in the Octagon, earning wins against the likes of BJ Penn, Paul Daley, and Lawler.
