Jorge Masvidal is doing his best to entice Conor McGregor into a fight.

After lobbing some harsh criticism toward the Irishman over the weekend, McGregor (22-6 MMA, 10-4 UFC) took to social media on Monday and fired back at Masvidal (35-16 MMA, 12-9 UFC).

McGregor tweeted then deleted saying Masvidal is “an absolute pigeon brain” and is “stupid beyond belief” (via Twitter):

Conor McGregor doesn’t think Jorge Masvidal is very intelligent.

An absolute pigeon brain this guy is. Stupid beyond belief.

Unsurprisingly, the insult from the former two-division UFC champion McGregor prompted a response from “BMF” champion Masvidal.

The reply was a clear attempt to set up a future matchup, with Masvidal arguing he would be the most high-profile matchup of McGregor’s illustrious career (via Twitter):

This pea brain is the biggest fight of your life. So you’re either too scared or too stupid to get this check

The idea of a McGregor vs. Masvidal fight is nothing new, as they are two of the most famous fighters in the sport. In the past, UFC president Dana White has dismissed the possibility of pairing them together, arguing that Masvidal holds too much of a size advantage of “The Notorious.”

McGregor hasn’t seen action since July 2021, when he suffered a broken leg in his trilogy fight with Dustin Poirier at UFC 264. White has said repeatedly that McGregor is expected to return this year, but reports have mentioned his comeback may be held off until 2023.

When he does come back, though, McGregor has said it’s his intention to compete at welterweight. That’s the division where Masvidal resides, although “Gamebred” is currently on a three-fight losing skid with two defeats to champion Kamaru Usman and another against rival Colby Covington.

Masvidal is currently tied up in a legal battle that came in the fallout of his unanimous decision loss to Covington at UFC 272 in March. He allegedly sucker-punched his former teammate outside a Miami hotspot, which resulted in multiple felony charges.
