Having matched up with a bevy of high-profile opponents in his 12-fight run with the UFC, Gegard Mousasi’s move to Bellator could open up fresh possibilities for him at both middleweight and light heavyweight. One name who has already discussed jumping up to 185 pounds to take on Mousasi is No. 1 welterweight title contender Rory MacDonald.

MacDonald recently told MMA Fighting that he’d be interested in taking on Mousasi should they both successfully claim titles in their respective divisions. “The Red King” is scheduled to challenge welterweight champion Douglas Lima at Bellator 192 on Jan. 20, while Mousasi is expected to contend for the middleweight championship at some point in the future.

Asked what he thinks of MacDonald’s plan during a recent episode of The MMA Hour, Mousasi dismissed chatter of a superfight for now.

“Rory MacDonald can get it himself,” Mousasi said. “Let him win his fight and then let him talk. He shouldn’t talk, he’s an idiot. He looks like a mass murderer. He should shut his mouth.”

Mousasi’s response was also prompted by MacDonald taking some shots at Mousasi’s recent promotional debut. In the Bellator 185 main event, Mousasi took a unanimous decision over Alexander Shlemenko in a contest that saw Shlemenko injure Mousasi’s eye early on and finish strong in the third round to nearly steal the scorecards.

In MacDonald’s eyes, the judges got the call wrong:

shlemenko won that fight clearly, shame he didnt get it officially on the decision — Rory MacDonald (@rory_macdonald) October 21, 2017

That tweet didn’t sit well with Mousasi, and he advised MacDonald to keep his thoughts to himself.

“He’s a weird guy,” Mousasi said. “Let him talk. Let him win his fights. He has his own bad performances, so he shouldn’t talk about me.”

“He’s a Canadian, I thought Canadians were more polite with that,” Mousasi continued. “He looks weird. Let him change his face before he talks.”

Before any issues with MacDonald can be resolved, Mousasi still has to deal with getting surgery to fix the orbital bone that was damaged by Shlemenko, not to mention his own aspirations for Bellator gold.

Current middleweight champion Rafael Carvalho defends his title against Alessio Sakara at Bellator 190 in Florence, Italy on Dec. 9 and Mousasi will be paying close attention to the outcome of that fight, should he be pegged as the next challenger.

“I’m going to watch the fight,” Mousasi said. “I’m going to take some time off and whoever is next, whenever they give me the fight, I’m not in any hurry.”
