A public feud is brewing between Donald Cerrone and the Jackson Wink MMA gym, and Mike Perry is standing by his new team.

Cerrone said earlier this week that his relationship with the New Mexico gym that he’s called home for years has become fractured due to what he perceives to be a mishandling of the business by coach Mike Winkeljohn. According to Cerrone, Winkeljohn lowered the quality of the training there by allowing anyone, regardless of experience, to come in and work with the pros so long as they paid their membership fee, and also of kicking Cerrone out of the gym when it was announced that he would be fighting Perry at UFC Denver on Nov. 10.

Cerrone alleges that Winklejohn told him he wouldn’t be welcome to set up his camp at Jackson Wink for the Perry bout, but Winkeljohn responded by saying that it was Cerrone establishing his own gym, the BMF Ranch, that played a major part in the deterioration of their relationship.

Now Perry, who began training with the Jackson Wink team earlier this year ahead of his most recent fight against Paul Felder, has weighed in. Initially tweeting about having YouTube celebrity Logan Paul come to the gym to train, Perry alluded to Cerrone’s accusation that they were literally bringing “bums” off the street by taking pride in the insult.

He then addressed Cerrone directly, claiming Cerrone doesn’t know what it’s like to have money problems and mentioning that he was glad “Cowboy” did not die in a recent cave diving incident. Perry then promised to give Cerrone a “Spartan beautiful death”.

Perry also recorded a video for Cerrone, shouting “I’m coming for you! (growl) I’m coming for you in front of the whole world, motherf**ker! You earned it. You earned it.”

Cerrone fights Perry in the welterweight co-main event of UFC Fight Night 139 at the Pepsi Center in Denver.
