CONOR McGREGOR could fight Terence Crawford - in boxing AND UFC.
Crawford's promoter Bob Arum believes a two-fight deal can be set up for two of sport's pound-for-pound best.
And he revealed that talks are set to begin with UFC supremo Dana White.
Crawford is unbeaten as a boxer with 36 straight wins and according to Arum has a "wrestling background".
His last fight was an impressive ninth-round stoppage of previously undefeated Egidijus Kavaliauskas in December.
McGregor, meanwhile, dipped his toe into boxing when he fought ring legend Floyd Mayweather in 2017 but was stopped in the 10th round.
Last weekend he made his glorious return to UFC after 15 months out with a stunning 40-second KO win against Donald Cerrone.
PACQUAIO WANTS MCGREGOR SCRAP
The Irishman has since been rumoured to be chasing a rematch against Mayweather, The Money seems up for that too, or even a fight against WBA super-welterweight world champ Manny Pacquiao.
But legendary promoter Arum wants The Notorious to fight his man in sporting crossover extravaganza.
Speaking on the TalkBox Boxing podcast, the 88-year-old said: “You see Conor McGregor talking about Mayweather and talking about Pacquiao.
“I’d love to have Crawford fight Conor McGregor, once MMA rules, and once boxing rules.
“I think Crawford has a wrestling background, and he wouldn’t be averse to fighting McGregor with MMA and UFC rules.
“So that’s something that has occurred to use in the last couple of days, and we’ll be pursuing it with Dana White."
SunSport exclusively revealed that McGregor is indeed being chased by boxing legend Pacquiao - but the Filipino wants a rematch against Mayweather first.

His promotional partner Sean Gibbons told SunSport: "As per a fight with the Senator and Conor McGregor - Conor has mentioned it a few times and if there was interest from the fans the Senator would consider the fight for sure.
“There were talks in the past. The Senator is really looking at a lot of different options and hope in the coming weeks to finalise something.
“Floyd Mayweather put it out himself in an interview that he is coming back in 2020 and one of the fights will be the Senator.”
