Bloodthirsty Covington: Colby intends to leave Usman 'in a pool of blood'
"I'm going to leave him lying around in a pool of his own blood. I'm going to make welterweight division great again. And he can not stop me. I'm going to show him that we are on different levels. He is the second level, and I am the first one. And we all know what happens when guys of different levels fight."
