Zuffa Boxing launches January 23 at the UFC Apex in Las Vegas with Callum Walsh (15-0, 11 KOs) facing Carlos Ocampo (38-3, 26 KOs) in a ten-round junior middleweight bout. The card features three main fights, each scheduled for ten rounds . Walsh has been getting steady television time over the past year, but Ocampo has been in with better opposition and knows how to make fights ugly when he needs to. He doesn’t fold in the middle rounds, which means Walsh needs to keep his feet under him when the finish doesn’t come early and the work becomes more about setting traps than landing clean power shots.
The fight streams exclusively on Paramount+ at no additional cost for subscribers.
What makes this interesting is whether Walsh can maintain his footwork and hand speed once Ocampo starts leaning on him and forcing exchanges in the pocket. Ocampo has the kind of chin that lets him walk through shots most prospects rely on to get rid of opponents. If Walsh starts reaching or drops his hands looking for counters, Ocampo will make him pay coming in.

Walsh (15-0, 11 KOs) has been getting steady television exposure, but Ocampo (38-3, 26 KOs) has faced better opposition and can make fights messy when necessary. Ocampo doesn’t collapse in middle rounds, which forces Walsh to set traps rather than rely on clean power shots when early finishes don’t materialize.

Rodriguez Needs To Handle Phone Booth Work
The co-main event features Olympic bronze medalist Misael Rodriguez against Austin Deanda in a ten-round middleweight bout. Rodriguez is still adjusting to the professional rhythm after years working three-round amateur rounds. Deanda fights best when he’s smothering distance and forcing inside exchanges. He throws short hooks to the body, ties up when he needs a breather, and turns bouts into wars of attrition.
Sandoval Gets His First Real Durability Test
The main card opens with Cain Sandoval against Julian Rodriguez in a ten-round welterweight bout. Sandoval enters unbeaten and has stopped several opponents early, but Julian Rodriguez has the kind of experience that forces adjustments between rounds. He absorbs punishment well, stays composed when hurt, and knows how to steal rounds late when opponents start fading. This bout shows whether Sandoval can maintain his punch selection and defensive responsibility when the knockout doesn’t arrive by round five and fatigue starts affecting his timing.

The UFC Apex strips away crowd energy, which means fighters can’t ride atmosphere when their legs get heavy or their punch output drops. What you see is pure execution under fatigue.
