Bellator has cut ties with the fighter known as War Machine following an alleged run-in involving his girlfriend.

Jon Koppenhaver, a former UFC fighter, is the “primary suspect” in a three-person altercation at his Las Vegas home on Friday involving War Machine and his girlfriend, Christy Mack, who is a porn star. According to a report by TMZ Sports, two of the people involved suffered injuries, though they are not believed to be life-threatening.

The names of the victims was not released, but both were taken to the hospital – and one was described as the fighter’s “significant other.”

Bellator sent out a release indicating War Machine had been cut from the desk of president Scott Coker:

“We have a zero tolerance policy here at Bellator when it relates to any form of domestic violence, and after learning of this latest incident involving Jon Koppenhaver, War Machine, Bellator is releasing him from him promotional contract with the organization.”

War Machine served a year in jail after a bar fight in San Diego in 2010. He fought for the UFC in 2007-08, going 1-1. Koppenhaver was also a cast member on Season 6 of The Ultimate Fighter, stepping in as a replacement.

His most recent fight inside the cage came last October when he lost to Ron Kesler via technical submission at Bellator 104. Prior to that, War Machine had won three straight, including two fights in Bellator and a third round TKO vs. Roger Huerta.

Mack has starred alongside War Machine in several adult films. The two have been together since last year and were featured in the January 2014 edition of “Hustler” together.

Mack’s personal Twitter page posted a picture Friday evening that stated “Hey guys I won’t be attending the Art & Ink show at the South Point Casino this weekend. I had a personal emergency come up BUT please still go support all of the artists and great people at the show!”

For Koppenhaver, this is just the latest in a long list of assault convictions that started in 2007 when he he was found guilty of striking a man in the face and choking him unconscious. He also had run-ins in 2008, three times in 2009 and his 2010 arrest that resulted in jail time.

His last post on Twitter came early Thursday morning to which he wrote “I can’t believe this…I must be cursed.”

The incident involving War Machine comes just days after another former UFC fighter, Josh Grispi, was arrested twice in the span of four days for violence against his wife.
