Marco TuliovsChristian Duncan

England's Christian Leroy Duncan brings serious momentum into this middleweight clash, riding a two-fight win streak that includes a first-round knockout of Eryk Anders in August. The switch-stance fighter from Range Martial Arts Academy has shown he can finish fights in multiple ways—three of his last four wins came by stoppage. Brazil's Marco Tulio is equally hot right now.

The Chute Boxe product has back-to-back knockout wins in 2025, stopping Ihor Potieria in January and Tresean Gore in April. Both finishes came from punches, showcasing the power that's made him dangerous at 185 pounds. This matchup pits two finishers against each other, both comfortable trading leather and hunting for the knockout.

Duncan's ability to switch stances adds a wrinkle that could disrupt Tulio's orthodox rhythm. The question is whether Duncan's more varied finishing arsenal—he's stopped opponents at distance, in the clinch, and from back control—gives him an edge over Tulio's straightforward power punching. With both fighters coming off knockout victories and neither showing much interest in decisions, something's got to give in Las Vegas.
