Watch: Colby Covington finally reveals what he actually told Kamaru Usman after their UFC 268 war

Colby Covington vs. Kamaru Usman at UFC 268 delivered as expected. The rematch, nearly two years in the making, saw 'The Nigerian Nightmare' come up victorious via unanimous decision.

Covington, for his part, showed the heart of a warrior. Despite being knocked down in the second round of the fight, 'Chaos' came roaring back in the third and fourth rounds. However, Usman did just enough to secure victory and go 2-0 in his rivalry with Covington. It was also the welterweight champ's fifth straight title defense and fifteenth consecutive win in the UFC.

There was a moment of respect between the two immediately after the fight. It took the cheeky one-liner, "You can kiss later," from referee Dan Miragliotta to separate the two. In a recent interview with Submission Radio, Covington jokingly revealed exactly what he told Usman during the exchange.

'Chaos' said:

"I went up to him, I'm like, 'Marty, come here. Come here, Marty. Little closer. Closer. Marty, little closer. Use promo code: Colby at mybookie.ag.'"

It is worth noting that Covington has been a long-time endorser of My Bookie - one of the biggest sportsbook sites in the world.
