Kattan, a Saturday Night Live alum, and Bolton, a professional bull rider-turned-model, have signed on for the Spring 2017 edition of Dancing with the Stars, which premieres March 20 on ABC, Peoplereported.
Kattan is best known for his skits with Will Ferrell on Saturday Night Live as well as his character Bob on the first four seasons of The Middle.
The 46-year-old comedian and actor also made a name for himself by playing Doug Butabi in the hilarious movie A Night at the Roxbury.
Bolton, 29, became a model following a life-threatening accident while bull riding in a January 2016 competition.
Bolton flipped off the backside of a bull and then got trampled by the wild animal, snapping his C2 vertebra in his neck.
According toGQ magazine, Bolton was paralyzed for 24 hours and underwent a six-hour surgery but shocked the world when he was able to walk again three days later.
Doctors reportedly told Bolton that 95 percent of people with his injuries never walk again.
Despite the athlete's desire to continue riding, he was done after that and began pursuing modeling as a career.
