UFC legends Nate Diaz and Jorge Masvidal will take to the boxing ring in the early hours of Sunday morning as they look to settle their long-standing feud in California.
(Odds will display when markets are available)
The two bitter rivals squared off at UFC 244 back in 2019, a bout in which Masvidal prevailed in after securing a third round TKO success as a result of a heavy cut above Diaz's right eye.
Five years on, the two are set to run it back for a second time - only this time inside a boxing ring.
Masvidal has been installed as the odds on 5/14 favourite to extend his unbeaten boxing record to 2-0, with the Floridian priced up at 12/5 to replicate his UFC stoppage victory over Diaz.
The California native, Diaz, meanwhile, is the 43/20 outsider, with his best hopes of victory seemingly coming on the scorecards at 4/1, significantly shorter than the 15/2 on offer for a KO / TKO victory.
The 10 round bout will represent just the second time that either fighter has participated in professional boxing fight.
Diaz's sole dust-up ending in a points loss to Jake Paul, whilst Masvidal's boxing debut - almost two decades ago - saw him chalk up a judges' decision success over Joseph Benjamin.
This weekend's showdown, which is scheduled to get underway at around 02:00 (BST) time and streamed live on Fanmio, was originally set to take place in June, before being rescheduled to avoid clashing with the mammoth Queensberry vs Matchroom's card in Saudi Arabia and UFC 302.
