Get Tickets — from $45Dempster vs. Dubois
Dempster is a knockout finisher, one KO in two fights, and she trains out of Vegas. Home crowd will be loud. Dubois has the wrestling background and the aggression to match her. That win at Power Slap 19 over Dodson was decisive. This fight is competitive on paper, and Power Slap fights tend to resolve fast.
Middleweight and Welterweight Titles
Middleweight champion Isaih Quinones of Lancaster, California (5-3, 4 KOs) defends against Stunt Marshall of Atlanta (3-0, 3 KOs). Quinones just got the title back in a trilogy against Branden Bordeaux. Marshall has three fights, three knockouts. Nobody has lasted the distance with him yet.
The welterweight title match puts Cole “Full Send” Young (4-2-1, 2 KOs) out of Canaseraga, New York, against Brandon “The Ripper” Rhodes (5-3, 1 KO) of Denver. Young won the middleweight world title at Power Slap 17. Rhodes picked up TKO wins over Azael Rodriguez at Power Slap 18 and Trenten Bordeaux at Power Slap 15.
Three title fights on one card during UFC International Fight Week. The Chelsea holds around 1,500. Seats are close.
Frank Lamicella, CEO of Thrill Sports, called it the biggest stage in combat sports. The card backs it up.
