WBC heavyweight world champion Deontay Wilder is now in hot water with the World Boxing Council, after the boxer made numerous statements regarding his desire to kill opponent Dominic Breazeale in the ring.
WBC president Mauricio Sulaiman said the comments were "regrettable" and against the organisation's ethics.
Wilder, 33, will make a mandatory defense against Breazeale on Saturday night at the Barclays Center in Brooklyn, New York.
Sulaiman said: "I have seen Deontay Wilder comments which are regrettable and completely against the spirit of our sport. I have known Wilder for a long time and he is not the person he portrays in such comments. His metaphors are against the WBC code of ethics and will be addressed in a hearing."
Wilder's statements have shocked a lot of people, and he's made similar statements in the past.
"Hey, Dominic Breazeale asked for this," Wilder told reporters. "I didn't go seek him, he sought me so if [death] comes, it comes. This is a brutal sport, this is not a gentleman's sport. I keep saying this is not a gentleman's sport. We don't ask to hit each other in the face but we does anyway.
"You can ask any doctor around the world and he'll tell you the head isn't supposed to be hit. Anybody can go and in this particular time we have bad blood against each other. This is the only sport where you can kill a man and get paid for it at the same time. It's legal, so why not use my right to do so? His life is on the line for this fight and I do mean his life. I'm still trying to get me a body on my record."
Breazeale's trainer Virgil Hunter said the champion risked his legacy with "irresponsible" comments.
