Deontay Wilder has apologised if a punch he landed on a mascot on a television show led to an injury to the person inside the costume.

The WBC heavyweight champion floored the mascot, wearing a sombrero and a moustache, with one punch after apparently being invited to show off his power on the Spanish language Nacion ESPN.

Reports circulated that the recipient of the punch had suffered a broken jaw, while Wilder denied he was unaware there was anyone in the costume.

A contrite Wilder has offered the mascot tickets to his upcoming bout against Tyson Fury on December 1 in Los Angeles.

He wrote in an Instagram post: “Anything headlining I didn’t know a “Human Being” was in there is just straight “Click Baiting” like come on now, I guess the Mascot rolled out there. show so respect!

“I sincerely apologize to the brave man that was injured (if this is true) I have the up most high respect for him, his participation, willingness and courage.

“If this is true @nacionespn I personally would like to invite him to my Dec.1 fight. Word Is Bond.”

The build-up to Wilder vs Fury has been different to say the very least. 

From the three press conferences they had in America and the UK, to the appearances on chat shows, the fight prep has really had it all.

However, Wilder appearing on a TV show and punching a mascot, before having a staredown with a dummy certainly leads the way in terms of random events prior to fight night.

Despite the reports emerging stating that an individual had sustained a broken jaw from Wilder's punch, an ESPN representative has moved to deny those claims.

“Reports are innacurate. No injury was caused to the Mascot performer during the Nación ESPN segment,” an ESPN representative told TheWrap Sunday.

He may not have broken the mascot's jaw, but he'll certainly be hoping to inflict damage onto Fury come December 1.
