Donald Cerrone recently opened up about his rift with coach Mike Winkeljohn that seems to have been simmering for a while now. According to Cowboy, who has trained at the famed Albuquerque camp for majority of his career, Winkeljohn merged and eventually turned the gym into a “puppy mill” that values money over loyalty.

“Loyalty is two sides,” Winkeljohn told MMA Junkie in response to Cerrone. “Cowboy is not loyal to anybody in the gym. He’s on his own. He does his own thing. He has not, from what I can remember in the last 10 years, ever helped anybody out with their own camp. He’s as narcissistic as they come.”

Winkeljohn says that Cerrone has drawn fighters and coaches away to train at his BMF Ranch, while not helping out at the main Jackson Wink team. He thinks about “100 percent” of those fighters have lost, which has lowered their overall winning percentage.

While Cerrone states that he felt betrayed that they sided with his next opponent in Mike Perry over him, Winkeljohn states that the “divide” in the gym has long been caused by Cowboy himself.

“I put up with it for a long time because Greg has the biggest heart in the world,” Winkeljohn said. “He’s like my little brother. But at the same time, it was causing division.

“If Perry wasn’t at my gym, I’m so much happier now that I got rid of the division in my gym (and) somebody that doesn’t want to help others and wants to do his own thing. It has absolutely nothing to do with Perry, and everything to do with Perry.

“What would ‘Cowboy’ do if it was his gym? Well let me think,” he said. “If I wanted to go into his gym use it when I wanted to, not be respectful, not help others, pull people and coaches away from the gym, and do things for myself, and then tell the new gym not to work with this person they’ve been working with because it’s all about yourself, what would ‘Cowboy’ do? I know what ‘Cowboy’ would do: The same thing I did, and that was basically, ‘Sorry kids, (expletive) that.’”

Cerrone faces Perry as the co-headliner of UFC Fight Night 139 on November 10. According to Perry, Winkeljohn and others will be in his corner, while Greg Jackson will remain in Cerrone’s.
