WSOF 23: Two Changes Made To Friday’s Preliminary Bout Card

Preliminary fight card streams live on prior to five-bout telecast on NBCSN on Friday, Sept. 18 from Comerica Theatre in Phoenix


LAS VEGAS (September 14, 2015) – Two Tucson, Ariz.-based fighting prospects – Kamuela Kirk and Brian Grinnell – have been given the shot of a lifetime after injuries have rendered Isaac Vallie-Flagg and Kelvin Tiller ineligible to compete in their respective  “WSOF 23: Gaethje vs. Palomino II” preliminary card bout commitments at Comerica Theatre in Phoenix, Ariz. on Friday, Sept. 18.

Kirk (4-1) will replace Vallie-Flagg, who sustained an elbow injury, in the scheduled lightweight (155 pounds) contest against Estevan Payan (16-8) of Tempe, Ariz., and Grinnell (8-6) will fill in for Tiller in the scheduled middleweight (185 pounds) matchup against undefeated Vagab Vagabov (19-0) of Dagestan, Russia.

The 21-year-old Kirk, who will make his fourth start of 2015, is coming off of a powerful performance on July 19, when he scored a first round (3:17) TKO on Edgar Escarrega with a barrage of knee strikes.

Kirk produced submission victories in each of his first three starts.  His only defeat, thus far, came via split decision in February.

Originally from Shawnee, Okla., the 27-year-old Grinnell (8-6) is an expert on the mat who has claimed 6 of his 8 professional career wins by way of submission.   In his latest effort, a July 24 matchup against Levi Queen, Grinnell forced Queen to tap out in the first round (2:59) of battle.
