Karate Combat Heavyweight champion — and former UFC fighter — Sam Alvey faced off with terrifying Cuban knockout artist Robelis Despaigne at the conclusion of the Karate Combat 58 official weigh-ins this morning in Miami, Florida. The two collide tomorrow night in a championship main event that promises pure chaos.
IIn the co-main event, Morocco’s Oussama Assli meets James Honey for the KC Welterweight title. The card also features several familiar names, including Chris Barnett — making his Karate Combat debut after his UFC release — Lorenz Larkin, and the always-entertaining Brandon Jenkins.
Watch the staredowns below:
Alvey enters the fight riding high after scoring an upset second-round knockout over kickboxing legend Tyrone Spong (watch highlights). He’s now 4-0-1 inside the Karate Combat pit and enjoying a career resurgence.
Despaigne, meanwhile, has lived up to his monstrous reputation, knocking out his first three KC opponents in a combined 30 seconds. He earned his title shot by running through a one-night Heavyweight tournament, defeating Saulo Cavalari, Tim Johnson, and Zac Pauga (watch highlights).
“Smilin’ Sam” knows he’s facing a mountain of a man — literally.
“This is a legacy kind of fight. When I’m old and grey and talking to my great-grandchildren, I’ll be able to tell them I beat Goliath. I literally beat a Goliath,” Alvey told MMAFighting. “I beat a man who is five or six inches taller than me with a reach that is 10 inches longer than mine. It’s crazy how long this man is. But they can say what they want — big tree, fall hard. I’ll make that happen.”
Karate Combat 58 will stream for free on YouTube on Fri., Dec. 5, 2025, right here.
