UFC star Kamaru Usman says Dana White offered him a fight with Colby Covington next month ... and he's waiting on Donald Trump's favorite fighter to sign the contract.
Both fighters have been dying to get a shot at the welterweight champ Tyron Woodley -- and it seems the winner of the proposed January 19 bout would get their wish.
TMZ Sports talked to Usman ... who tells us Dana called this week and made the offer.
Kamaru ain't exactly confident the fight will actually happen ... saying Colby has refused to accept the match on 4 other occasions in the past.
So yeah, Kamaru and Colby hate each other ... and straight-up, Usman says Covington is scared.
If he accepts, Usman vs. Covington would join a bunch of solid fights on the first UFC event on ESPN -- including Paige VanZant vs. Rachael Ostovich and Greg Hardy vs. Allen Crowder.
Usman just dominated Rafael dos Anjos when they clashed on Saturday night at "The Ultimate Fighter" finale.
Covington's last fight was also against RDA -- Colby scored the "W" in a 5-round decision at UFC 225 back in June.
After the fight, Colby underwent surgery to correct a nasal issue. He visited Trump at the White House in August and took a pic with POTUS while Donald held the UFC interim welterweight championship belt over his shoulder.
We reached out to Covington for comment ... so far, no word back.
