Conor McGregor issued a warning to Ryan Garcia.

The UFC star, like most of the combat sports world, found out earlier this week that Garcia tested positive for banned substances stemming from his upset win over Devin Haney on April 20 in Brooklyn. As McGregor often does, he went on Twitter to give a detailed response to one of the week’s biggest stories — and also lumped in current UFC bantamweight champion Sean O’Malley.

“Cheated the weight and was juiced, lifetime ban,” McGregor said in a now deleted tweet. “Sad to see, sad to say. Sad and a bit sick. Don’t come near me if I see you ever Ryan Garcia. I am actually disgusted. This ostarine it reminds me of Sean O’Malley — was on that as well. I don’t like this, I’ll bust yous both up. Do yous want to spar? I will set flights right now for you both todo a full-on spar each. Hotel, Black Forge Inn, the lot. Let’s spar O’Malley and Garcia, two little ostarine heads. I’ll ride you both like yous are ostriches. [What the f*ck] is up? What do you think you are at?

“If I was Haney’s dad, you’re dead no matter what for doing that. Crazy. What the f*ck happened to you, you little fool. Get your head together [because I’m] going to smash it in with elbows if you don’t. Fair play Devin, well done. Your performance has just become even more heroic. Bravo. Get your head together [Garcia] or kill yourself.”

Garcia has continuously denied any wrongdoing, and believes he’ll silence a lot of critics in the coming weeks. As of now, no penalty has been given to Garcia, nor has a decision been made on whether or not his majority decision win over Haney will stand.

“King Ryan” was quick to respond on social media, warning McGregor that there will be a confrontation if they cross paths in person.

“If I see Connor McGregor, I’m going to break your weak-ass ankle,” Garcia wrote. “You ran from being tested [because] you were on [steroids]. Road House or ROIDRAGE FUDGE CONNOR CACA BRAIN.”

He later added, “It’s war on the McGregors,” and then suggested a bare-knuckle boxing bout with McGregor.
