MMA fans will have a huge red circle in their calendars around March 5.
Jorge Masvidal and Colby Covington will be going toe-to-toe in one of the most highly-anticipated grudge matches ever.
This is a fight that has been talked up and spat out in recent years; the circumstances weren't quite right for either man, but now it is the perfect match-up at the perfect time.
Francis Ngannou's upcoming clash with Ciryl Gane is being labelled as a friends-turned-foes encounter at UFC 270 next Saturday but their split is nothing compared to Masvidal and Covington.

Now the friends-turned-rivals will meet in March to settle their bitter grudge
So much has been said by both men about how they went from gym buddies to bitter rivals and it is worth a timely reminder of just why there is so much bad blood between them.
Let's start with the completely contrasting routes to the top.
Covington was a college wrestling star earning All-American honours while Masvidal shot to YouTube fame as a backyard fighter during the Kimbo Slice era.
'Street Jesus' is about as different as it gets from Covington but their paths, however contrasting, both led them to American Top Team.
The Florida-based gym was where both welterweights honed their craft and proved to be the breeding ground for so many top UFC talents.
Being in the same weight class, in the same gym, of course they both developed a rapport.
While training sessions were competitive, Covington and Masvidal used to have a close bond
'We were pushing each other in the gym. We'd yell in the gym, "Hey, who's gonna be the first fighter to get a million-dollar fight," this and that,' Covington previously told Submission Radio. 'We were competing to push each other to these great limits.'
There are numerous pictures of the pair together at the time, both in the gym and out socially, so it certainly seems they were close.
But in October 2017, Covington took a new direction having previously been told by the UFC he was too boring and at risk of being cut.
After a huge win over Brazilian favourite Demian Maia in his homeland, the American played the pantomime villain, yelling to the crowd: 'Brazil, you're a dump! All you filthy animals suck.
'I've got one thing to say: [former champion] Tyron Woodley, I'm coming for you. If you don't answer the front door, I'm going to knock it in and I'm going to take what's mine, that welterweight belt!'
Covington said the pair pushed each other in every single training session together
Covington and Masvidal don't agree on much but they concur that the Maia fight was a fork in the road moment.
'Chaos' thinks Masvidal was envious of all the publicity his team-mate was having as the UFC's new heel.
'He's the type of guy that when you are doing something for him, he will use you,' Covington told Ariel Helwani's MMA Show. 'As long as you are doing better than him and you are not helping him out anymore, then he doesn't care about you.
'And that's exactly what happened
