Former UFC heavyweight champion Frank Mir won't be making his return to mixed martial arts competition anytime soon.
Mir was among the veteran names to sign with the newly created Global Fight League ahead of its inaugural draft this past January. The 45-year-old was ultimately picked alongside Andrei Arlovski for Team Los Angeles.
And Mir was also among the first to have their opening matchup announced on social media, with the Las Vegas native penciled in to share the cage with a fellow former UFC champ in Fabrício Werdum of Team São Paulo.
But those plans will be put on hold after Mir revealed in a post on Instagram that he "underwent an emergency spinal fusion and laminectomy of (his) entire thoracic spine."
