LAS VEGAS (AP) — Ex-pro wrestler CM Punk will make his long-anticipated UFC debut when he fights Mickey Gall on Sept. 10.

The mixed martial arts promotion announced the welterweight matchup for UFC 203 in Cleveland on Thursday.

Punk’s real name is Phil Brooks. He is one of the most popular professional wrestlers of recent years, but he quit that non-competitive pursuit and began to pursue an MMA career in December 2014.

The 37-year-old Punk’s debut has been delayed twice while he dealt with injuries. He has long been expected to fight Gall (2-0), a relatively untested prospect.

UFC 203 is headlined by heavyweight champion Stipe Miocic’s first title defense against Alistair Overeem.
