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.
