Bloody Elbow has learned that yet another antitrust complaint has been filed against the UFC in the Northern California District Court, this time with former UFC fighters Kyle Kingsbury and Darren Uyenoyama named as the plaintiffs. This brings the total number of complaints filed against the UFC to five with eleven named plaintiffs asking to be class representatives in a class action lawsuit.

The lawsuit, which was filed on March 20, 2015, claims that "Through a series of anticompetitive, illicit and exclusionary acts, the UFC has illegally acquired, enhanced and maintained dominant position in the markets" for MMA events and fighters.

Kyle Kingsbury made his UFC debut against Tom Lawlor at The Ultimate Fighter Season 8 Finale, after having been a contestant on the reality show. He would have 8 more fights in the promotion, 4 wins and 5 loses, before retiring after a loss to Patrick Cummings on the July 26, 2014 UFC on Fox event.

Darren Uyenoyama fought four times in the UFC, debuting on the prelims of the first FOX event, where he defeated Norifumi Yamamoto. Uyenoyama would win his next bout before losing two in a row and being released.

Worth noting, as the UFC tries to have the venue moved from San Jose, California to Las Vegas, Nevada, is that Uyenoyama is a resident of San Francisco and Kingsbury is a resident of Sunnyvale, California, which is located in the Bay Area

The previously filed complaints, Le et al v. Zuffa, LLC, Vazquez et al v. Zuffa, LLC, Vera et al v. Zuffa, LLC. and Ruediger et al v. Zuffa, LLC named Cung Le, Jon Fitch, Nathan Quarry. Luis Javier Vazquez, Dennis Lloyd Hallman, Brandon Vera, Pablo Garza, Gabe Ruediger, and Mac Danzig as the plaintiffs. Counsel for the plaintiffs have filed a motion to consolidate these complaints and a hearing has been scheduled for June 11. The new case name would be "In Re: Ultimate Fighting Championship Antitrust Litigation."
