Valter Walker submits Zion Clark in main event at Karate Combat 59. In a highly unusual grappling showdown at Karate Combat 59 on Friday, February 13, 2026, Valter Walker earned a quick submission victory over Zion Clark in the event’s main event held at the Telemundo Center in Miami, Florida.
Walker secured the finish early with a rear-naked choke, continuing his dominant run in combat sports grappling. The match paired Walker, a UFC heavyweight known for his submission skills, particularly his string of heel hook finishes against Clark, a former collegiate wrestler born without legs due to Caudal regression syndrome. The size and weight difference between the two fighters was significant, turning the open-weight grappling match into a compelling spectacle.
Right from the start, Walker used his experience and physical advantage to control the pace. Although Clark impressed early by briefly taking Walker’s back in the opening moments, the larger grappler eventually took back control and worked to secure a dominant position. Once on Clark’s back, Walker locked in a tight rear-naked choke that forced Clark to tap, giving Walker a first-round submission win.
For Walker, the win further solidified his reputation as a top submissions grappler, capable of adapting his skills beyond his signature heel hooks. The victory also fueled post-fight drama: Walker publicly called out his brother, fellow UFC fighter Johnny Walker, suggesting the two meet in future competition, whether in Karate Combat or the UFC.
Also on the card, Monika Chochlikova takes on the Elisandra Ferreira for the Karate Combat strawweight title, while Uriah Hall faces Jayden Eynaud in a light heavyweight bout. A lightweight fight between Shahzaib Rind and Diego Brandao was scheduled to take place, as well, but Rind missed weight by five pounds, cancelling the bout.
