The two new additions are scheduled to debut against each other at WEC 37 on Dec. 3 at the Hard Rock Hotel & Casino in Las Vegas, according to a report by MMA Weekly.

Benavidez is a perfect 9-0 in his professional mixed martial arts career and raised his profile following a first round submission victory against Junya Kudo at DREAM 5 in Japan this past July. A member of Urijah Faber’s gym in Sacramento, Benavidez had originally been scheduled to fight against Norifumi “Kid” Yamamoto before he pulled off the card due to injury and was replaced by Kudo.

Martinez is 12-2 and a strong prospect in his own right. The Arizona native has competed in Canada for the TKO promotion and is currently the Rage in the Cage bantamweight champion. Martinez’s last bout took place for the Evolution MMA promotion this past October, where he submitted Joey Marimberga at 1:21 of round 3.

Benavidez and Martinez join a deep WEC bantamweight division that includes champion Miguel Torres, number one contender Manny Tapia, veteran Jeff Curran, prospect Will Ribiero, Brian Bowles, Marcos Galvao, Scott Jorgensen, Yoshiro Maeda, Rani Yahya, and Damacio Page.

Torres will be headling WEC 37 when he defends his title against Tapia with Ribiero and Bowles also in action against each other. Non-bantamweight bouts scheduled for the card include featherweights Akitoshi Tamura vs. Wagnney Fabiano, featherweights Josh Grispi vs. Diego Nunes, featherweights Hiroyuki Takaya vs. Cub Swanson, lightweights Shane Roller vs. Mike Budnik, welterweights Alex Serdyukov vs. Johny Hendricks, lightweights Bart Palaszewski vs. Alex Karalexis, and light heavyweights Mark Munoz vs. Ricardo Barros.

Both fighters are coming off of losses, Gouveia losing to Goran Reljic at UFC 84 in the second round via TKO. Before that, Gouveia had been on a nice winning streak, not having lost in the Octagon since dropping a unanimous decision loss to Keith Jardine in 2006.

Horn is coming off his second submission loss in a row in the UFC, this time at the hands of grappling wizard Dean Lister at The Ultimate Fighter 7 Finale. Until recently, Horn hadn’t been submitted in nearly seven years but has dropped three of his last four via submission.

Both fighters will be looking to get back on track and it’s possible that Gouveia could be trying his hand at a new weight class at 185 lbs. His frame is small for 205 lbs., especially at the top of the division and a cut to middleweight may do him well if that’s what weight the fight is being contested at.

It is not known whether Horn will be competing on a one-fight basis or if he’s been signed to a long-term contract.

Leites was scratched after suffering a hand injury while training.

Horn, who has fought in the UFC before, and even fought and lost in the main event of UFC 54 against Chuck Liddell, whom he had previously beaten at UFC 19 in 1999.

Horn has competed since 1996 and has compiled a documented record of 79-16-5, however, it’s widely accepted that he has competed well over 100 times throughout his career.
