Saturday’s UFC on ESPN 63 marks the return of the ever-polarizing Colby Covington , who has not competed since December 2023. While it’s unknown how much heat the Covington (17-4 MMA, 12-4 UFC) vs. Joaquin Buckley (20-6 MMA, 10-4 UFC) main event at Amalie Arena in Tampa, Fla. will have, there’s almost no question it won’t be Covington’s most intense career rivalry. That crown belongs to the “King of Miami,” Jorge Masvidal . Friends turned mortal enemies, Covington and Masvidal finally got their hands on each other at UFC 272 in March 2022
