“Mystic Mac” is back with a prediction for the UFC 257 main event.

Ahead of his lightweight rematch with Dustin Poirier (26-6 MMA, 18-5) this month, Conor McGregor has offered up his official estimation of what’s going to go down when the pair step inside the octagon.

After winning the first contest in less than two minutes at UFC 178 in September 2014, McGregor (22-4 MMA, 10-2 UFC) is expecting an even quicker second clash with “The Diamond.”

On a snippet of the upcoming UFC 257 “Countdown” show, the Irishman said he expects Poirier to fall within the first minute.

“I like Dustin. I think he’s a good fighter,” McGregor said. “He’s even a great fighter. But great is still levels below me. I’ll knock Dustin out inside 60 seconds.”

McGregor has a history of being accurate with his pre-fight predictions. It’s not always gone according to plan, but more often than not, he’s proved to be on point.

In less than two weeks, the MMA world will know if he can do it again when he steps in the octagon with Poirier at UFC 257, which takes place Jan. 23 at Etihad Arena in Abu Dhabi. The main card airs on pay-per-view following prelims on ESPN and ESPN+.
