Muhammad mocked McGregor.

Belal Muhammad, the UFC welterweight champion, has mocked Conor McGregor, who recently said he wants to take the championship belt away from him.

"He just wants to stay in the public eye and my fight was just announced. Now we're gaining momentum and he wants to put his name in it. He says stupid things - you can just watch him knowing he's on drugs and probably will never fight again. It's not even worth discussing, but I've always enjoyed making fun of McGregor - it's the easiest thing in the world. He gives so many reasons to be attacked, and he's not that good of a thrash-talker anymore. He's not that witty guy anymore, and he just keeps saying the same thing over and over again."
