Kamaru Usman says Jorge Masvidal's BMF belt IS on the line when they fight Saturday -- and he already knows where he'll keep it after he wins.
"After I go out there and beat his ass and ragdoll him, that sh*t is coming home with me so I can throw it in my closet."
Of course, Kamaru is the UFC's reigning welterweight champ -- and he was originally set to defend that belt against Gilbert Burns in the first main event on Fight Island.
But when Gilbert tested positive for COVID and pulled out the fight over the weekend -- Masvidal stepped in and took his place.
