Watch as boxing champion Deontay Wilder breaks jaw of mascot in promo stunt gone wrong

Heavyweight boxing champion Deontay Wilder has apologised after reportedly breaking the jaw of a mascot he punched during a US television appearance.

Wilder was doing a promotional appearance on Spanish language show Nacion ESPN to promote his upcoming fight with Tyson Fury when he punched a man dressed in a mascot suit.

The WBC heavyweight champion also denied he did not know there was a person in the suit.

"Anything headlining I didn't know a human being was in there is just straight click-baiting," Wilder said on Instagram.

"I sincerely apologise to the brave man that was injured (if this is true). I have the utmost respect for him, his participation, willingness and courage.”

Wilder said reports of the injury were true, he would like to invite the man to his fight on December 1 against Fury in Los Angeles where he will defend his title.
