It's been three times so far, and I think if Moreno beats Kai Kara-France again (yep they met at UFC 245: Usman vs Covington) they will go at it again.
Moreno is on the next UFC card
Personally, I am a fan of both these athletes and I am happy to see them both take on other contenders for a while but I would love to see them go at it again.
For me, the first 2 were fascinating, the third not so much.
How about you? Is three enough or would you campaign for a 4th?
