«Jackass» star Steve-O has never backed down from a challenge, which included a chokehold by a former UFC champion.

Michael Bisping, who is now a combat sports analyst, returned to the octagon at the UFC APEX Center in Las Vegas on Saturday for a challenge that Steve-O and YouTube star Stevewilldoit decided they wanted to participate in.

Along with current middleweight Marvin Vettori, the goal of the UFC fighters was to get Steve-O and Stevewilldoit to tap out a chokehold. Although Bisping and Vettori are retired from the sport, they were willing to have a little fun.

Bisping, 44, stepped up behind Steve-O and choked him from behind. Vettori did the same with Stevewilldoit.

While we can’t see if Steve tapped out or not, Steve-O let Bisping drive him to the canvas and knocked him unconscious.

It seemed like 11 seconds passed before Bisping was able to get Steve-O out, but he quickly got it back.

«Crazy bastard. Are you okay?» Bisping asked Steve-O on the canvas.

While it may have been a bit of a scary time for Bisping as he kept touching Steve-O to make sure he woke up, the professional stuntman has been through a lot worse as the «Jackass» franchise has shown.

Bisping enjoyed a successful career in the UFC, going 30-9 in his 39 matches with 18 knockouts, two submission wins and 10 decision wins. He held the UFC middleweight belt until Georges St-Pierre submitted him in a rear-naked choke (what a coincidence) on November 4, 2017.
