John Kavanagh, the head trainer for UFC superstar Conor McGregor, does not rule out the possibility of a boxing match with Paulie Malignaggi.

The two fighters have been traded words for well over a year - taking shots at each other during interviews and on social media.

Last August at T-Mobile Arena in Las Vegas, McGregor made his professional boxing debut - and suffered a ten round TKO defeat at the hands of Floyd Mayweather Jr. - who was coming off a near two-year layoff.

And to prepare for that fight, McGregor hired Malignaggi as a sparring partner.

The pairing turned sour - with Malignaggi leaving the camp after claiming that McGregor and his handlers were leaking photos and footage of their sparring sessions.

Earlier this month, McGregor made his return to the UFC for the first time in nearly two years - and he was submitted by his division rival Khabib Nurmagomedov.

The move for McGregor? It could be in the UFC. It could be in boxing.

And the idea of facing Malignaggi, to finally settle their beef, is not being ruled out.

“It is absolutely not out of the realms of possibilities,” Kavanagh said during an appearance on the Joe Rogan Experience.

“There are all sorts of crazy rumors going around the management team and the fight team about what might happen next. It could be boxing, it could be him [Malignaggi], it could be Floyd. All sorts of names are being thrown about.”

According to Malignaggi, the photos and released footage was manipulated to create the belief that McGregor gave him a beating.

He dared McGregor to release the video of the full sparring session - but that never happened.

Kavanagh revealed that a three part documentary, on McGregor, will soon debut on Netflix - and the entire 12 round sparring session in question, will be featured as part of that series.

“I think there is something being released on Netflix soon based around that fight and it’ll have all the rounds,” Kavanagh said. “We have the 12 rounds. As far as I’m aware, I just did an interview for it recently. I think it’s a three part documentary that’s going to be on Netflix soon. So people will get to make up their own minds about it.

“It turned out to be a great contest [when they sparred]. And I’ll say contest because it wasn’t a spar, they were talking the whole time. They were talking the whole time, Paulie was talking to me, he was talking to the cameraman, he was almost better than Conor at it, it was great to watch. Everybody had a great night, and I think they both actually bizarrely enjoyed it. It’s like Conor and Nate (Diaz). It’s Batman and The Joker, they both need each other. They hate each other, but they love each other.”
