Castaneda enters on a two-fight skid against Chris Gutierrez and Daniel Marcos, relying on his 69-inch reach advantage over the 5'3\" Russian's 65-inch span and well-rounded skillset with wins across KO, submission, and decision. Vologdin earned his contract via a violent Dana White's Contender Series knockout, showcasing explosive pressure but facing a step-up in competition. Castaneda missed bantamweight at 139 pounds on Friday weigh-ins, shifting to catchweight; no injuries reported, setting up a striker's banger with Vologdin's power posing upset threat to the lengthier American.",
