Fans have been desperate for the two to rematch since then but their paths never crossed before their respective retirements.

But now that both are no longer contracted to the UFC, the fight will be happening in a boxing ring.

The match will take place at light-heavyweight and consist of 10 rounds.

Masvidal retired from MMA after losing to Gilbert Burns in April 2023.

Diaz meanwhile finished his UFC career on a high, beating Tony Ferguson by submission in September 2022.

Diaz, 38, made his professional boxing debut last August, where he lost to YouTube star Jake Paul.

The announcement that Masvidal and Diaz will fight comes just days after Conor McGregor called Diaz out for a trilogy fight.

The Irishman took to Instagram to say: “I wish for this on Mexican Independence Day in the sphere. Chandler June. Diaz September. I have let this be known.”

But UFC supremo Dana White confirmed he has no interest in making the fight happen, by briefly saying: “Yeah, I’m not doing that fight.”

‘The Notorious’ has not fought since July 2021, when he broke his leg in a loss to Dustin Poirier.

McGregor recently broke his silence on being left out of the historic UFC 300, set to take place on April 13.

His prospective fight against Michael Chandler was tipped for top billing but he was snubbed by White.

On the 300 card, he said: “I love it! They done a tremendous job under difficult timing. I’m highly impressed.

“Some absolute cracking fights on the card.”
