The upcoming lightweight tournament at World Series of Fighting 25 acquired a pair of reserve bouts recently, as officials announced LaRue Burley vs. Joe Condon and Benny Madrid vs. Ramil Mustapayev.

Set for November 20 and the Comerica Theatre in Phoenix, the main card airs live on NBC Sports Network.

Mike Ricci, Brian Cobb, Luis Palomino, Rich Patishnock, Brian Foster, Joao Zeferino, Jorge Patino and Islam Mamedov will all square off in a one-night tournament to crown the new No. 1 contender to Justin Gaethje.

If anyone is unable to continue, Burley, Condon, Madrid and Mustapayev will fill that hole depending on who wins their respective matches.

“Our tournament lineup is officially complete with the addition of these matchups, and we are looking forward to having the four talented fighters selected for these two important fights, compete on this historic card and be prepared to enter the single-elimination contest if necessary,” said World Series of Fighting President Ray Sefo.

The 31-year-old Burley (6-1) of Gilbert, Ariz. is looking to return to form after suffering his first career blemish, a first round (:32) KO (punch) at the hands of accomplished veteran and one of the eight tournament contestants, Brian Foster, at WSOF 23 on September 18.

Prior to the defeat, Burley had emerged one of MMA’s hottest prospects, recording victories in his first six professional fights, including a third round (3:40) TKO (punches) of fellow rising star Bubba Jenkins, after an unbeaten career as an amateur. Four of Burley’s six career wins have come by way of (T)KO or submission.

Condon (12-8) of Victorville, Calif. is also looking to return to the win column in what will be his third start for World Series of Fighting, following a unanimous decision defeat to Nick Newell at WSOF 20 on April 10.

In his promotional debut on January 17, the 29-year-old Condon submitted Jonathan Nunez with a guillotine choke in the third round (4:22) of battle at WSOF 17.

The 35-year-old Madrid (8-3) of Phoenix is coming off a splendid, first round (1:26) submission (rear-naked choke) victory over Jeff Fletcher at WSOF 23. The win snapped a three-fight skid that came after Madrid had reeled off wins in his first seven professional career fights, a streak that spanned four years between 2009 and 2013.

Mustapayev (3-1) of Albuquerque, N.M. via Moscow, Russia will make his World Series of Fighting debut and will risk a perfect, 3-0 run that he is in the midst of this year.

A member of Greg Jackson’s and Mike Winklejohn’s famed fight team, Mustapayev is fresh off a stunning, first round (3:10) TKO (punches) of Jarel Askew in a matchup that took place on August 29.
