Injuries have forced Isaac Vallie-Flagg and Kelvin Tiller to withdraw from their respective bouts at WSOF 23 “Gaethje vs. Palomino 2.”
World Series of Fighting officials on Monday announced that both men have been removed from Friday’s card at Comerica Theatre in Phoenix, Ariz. Vallie-Flagg recently sustained an elbow injury; no specifics were given regarding Tiller’s injury.
Vallie-Flagg has been replaced by Tucson’s Kamuela Kirk, who will move up from featherweight to lightweight to face UFC and Bellator veteran Estevan Payan. Kirk has won four of his five professional fights with three submissions and one knockout, all inside the opening round.
