Deontay Wilder has wasted no time in putting Conor McGregor in his place after suggestions of a crossover fight between the two.

Wilder remains the WBC champion after a stunning seventh-round knockout victory over Luis Ortiz in Las Vegas on Saturday, whilst McGregor hasn't fought since his defeat to Khabib Nurmagomedov in October 2018.

The question was put to Wilder via a YouTuber during GQ's undercover series.

Wilder said in response: "Ah, man. Bad. You know, unfortunately that's a fantasy fight, and I am way too big for Conor McGregor right now.

"Did you see what Floyd [Mayweather] did to him? You know, it was a great fight overall.

"But I'm way too big for Conor, and unfortunately, we'll probably never fight.

"If it was boxing or MMA, I don't think it would be a chance.

Given that Wilder is 6"5 and considered one of the most brutal punchers in boxing history, McGregor at 5"7 might struggle to land anything close to a powerful shot.

Wilder supports this claim by saying: "You know, consider that, you know, I am the hardest-hitting puncher in the world or probably in the history of boxing. Period. You know, I don't think four ounce of gloves will make it even better.

"I'd probably seriously hurt someone with four-ounce gloves. And we'll keep it like that."

If both fighters would ever agree to it, this wouldn't be the first time McGregor has stepped into the ring as a boxer.

McGregor famously fought Floyd Mayweather in a showpiece fight in Vegas in 2017. Although it went to 10 rounds, and Mayweather won via TKO, it was considered to be a complete mismatch in terms of technical boxing ability.

Both men have their own fights to worry about in 2020 with Wilder likely to face Tyson Fury in their hugely anticipated rematch in February.

McGregor, meanwhile, is closing in on his comeback fight, but a date has yet to be decided.

Notorious has never been one to shy away from a challenge, but surely this would be one step too far for the Irishman.
