Why it matters

This matchup between the much larger Valter Walker and the smaller Zion Clark, who has competed at bantamweight, generated intrigue and uncertainty among fans about how the fight would play out. Walker's dominant performance and subsequent callout of his brother adds an interesting family dynamic to the Karate Combat promotion.

Walker initially struggled to find the right approach against the smaller Clark, who was able to briefly get to Walker's back early on. However, Walker eventually pressed the issue and was able to easily take Clark's back and secure the rear-naked choke submission. After the fight, Clark acknowledged the size difference but promised to do better against opponents his own size, while also calling for a rematch with Walker. Walker, meanwhile, expressed disappointment that his brother Johnny Walker did not come to support him and challenged him to a fight at the next Karate Combat event.
