Brock, a 34-year-old native of Boise, Idaho, owns a 22-8 career mark since beginning his career in 2006. His promotional debut is expected to be announced soon.
“Jesse is a true performer who has taken on some of the best fighters in his weight class, and he has clearly earned the opportunity to contend in our bantamweight division,” WSOF President Ray Sefo said in a release.
Brock will enter his WSOF debut on a six-fight winning streak. Most recently, he scored a third-round submission of Olly Bradstreet at Bellator 155 on May 20. In addition to Bellator, Brock has also competed for organizations such as Resurrection Fighting Alliance, Maximum Fighting Championship, Rage in the Cage, Shooto Brazil and Ring of Fire during a well-traveled career.
