CM Punk’s next battle will be on reality television, not the Octagon.

The WWE-headliner-turned-UFC-fighter will take part in MTV’s “The Challenge: Champs vs. Pros” this spring, MTV’s official website announced Monday. CM Punk and nine other well-known pro-sports figures will go head-to-head with former winners of MTV shows “Road Rules” and “Real World” in athletic competitions.

Among the other pro athletes competing are Olympian Lolo Jones, snowboarder Lindsey Jacobellis, former NFL linebacker Shawne Merriman and former WNBA player Candice Wiggins.

Each athlete has a chance to win $50,000 for a charity of their choosing. CM Punk is competing for PAWS Chicago, a no-kill animal shelter in his home city. The show premieres May 16.

Punk, 38, competed in his first UFC fight back in September, falling by first-round submission to Mickey Gall. The UFC signed him at the end of 2014 and he began training with Roufusport in Milwaukee in 2015. Punk, whose real name is Phil Brooks, retired from pro wrestling after a dispute with WWE in early 2014.

Punk was one of the biggest stars in that medium when he stepped away and the UFC paid him a $500,000 purse for the fight against Gall, which likely escalated to more than $1 million after bonuses. He is likely to compete again in the Octagon, though it is not clear when or against whom.
