Tickets on sale now

LAS VEGAS (October 17, 2015) –World Series of Fighting (WSOF.com) announced tonight during its live NBCSN telecast of “WSOF 24: Fitch vs. Okami,” the quarterfinal stage matchups and brackets for its historic, one-night, eight-man tournament that will crown its winner the new number one contender in the promotion’s coveted lightweight (155 pound) division, at “WSOF 25: Eight-Man Lightweight Tournament,” on Friday, Nov. 20, live on NBCSN at 9 p.m. ET/6 p.m. PT from Comerica Theatre in Phoenix, Ariz.

Additionally, a lightweight co-main event pitting Jason “The Kansas City Bandit” High against fellow battle-tested star and World Series of Fighting newcomer Estevan “El Terrible” Payan was announced for WSOF 25.

“We are excited about the star-studded lineup and incredible matchups we have assembled for the first World Series of Fighting one-night tournament in history,” said World Series of Fighting President Ray Sefo.  “Combined with an outstanding co-main event between Jason High and Estevan Payan, this is a must-see event for any fight fan.”

In one tournament bracket, Luis “Baboon” Palomino (23-11) of Miami, Fla., coming off another “Fight of the Month” performance at WSOF 23 in September, will square off with rising star Rich Patishnock (6-2) of East Stroudsberg, Pa., while Brian Foster (23-7) of Sallisaw, Okla., fresh off a thunderous, first round (:32) KO of previously unbeaten LaRue Burley at WSOF 23, will collide with streaking submission wizard Joao Zeferino (18-6) of Florianopolis, Santa Catarina, Brazil.

In the opposite bracket, wrestling and submission ace Brian “The Bandit” Cobb (20-8) of Bakersfield, Calif. will battle Firas Zahabi-trained Brazilian Jiu-Jitsu brown belt  Mike “The Martian” Ricci (10-4) of Montreal, Quebec, Canada, while Islam Mamedov (12-1) of Jersey City, N.J. via Derbent, Dagestan, Russia will put his phenomenal, 11-fight winning streak on the line against five-time, one-night tournament winner and Judo and Brazilian Jiu-Jitsu black belt Jorge “Macaco” Patino (38-15-2, 1 NC) of Houston, Texas via Sao Paulo, Brazil.

The winner of the quarterfinal stage bout between Palomino and Patishnock will meet the winner of the fight between Foster and Zeferino in the semifinal stage of the single-elimination affair, and the winner of the matchup between Cobb and Ricci will face the winner of the bout between Mamedov and Patino in the semifinal stage of the tournament.

The two semifinal stage victors will face off against each other for the tournament championship and the right to challenge reigning, undefeated World Series of Fighting lightweight champion Justin Gaethje.

High (18-5) of Kansas City, Mo. will look to establish his presence in the World Series of Fighting lightweight division after defeating top-level competition elsewhere in the U.S. as well as in Japan, where the 34-year-old made his initial mark in the sport by collecting wins in the now defunct DREAM and K-1 promotions, and followed up his stellar performances overseas with a perfect, 3-0 run in the Strikeforce cage.

Another former Strikeforce standout, the 33-year-old Payan (16-8, 1 NC) of Tempe, Ariz. has also scrapped with notable adversaries, and has imposed his will with dangerous punching power.  Payan is looking for his second straight victory after scoring a third round (2:45) KO on Roberto Young with a barrage of punches on June 6.

Priced from $29.99, tickets for “WSOF 25: Eight-Man Lightweight Tournament” are on sale at the Comerica Theatre box office as well as online at Ticketmaster.com and WSOF.com.
