Promotion for Tyson Fury's monster matchup with Deontay Wilder for the WBC heavyweight championship on December 1 is well and truly underway.The pair addressed the press for the first time earlier this week at a conference in London and even appeared on national television to talk about the fight.New footage taken backstage before their appearance on Good Morning Britain shows Wilder and Fury exchange words before stepping in front of the cameras.However, the footage shows that it appears the apparent animosity between the two is strictly business.When confronted by the Bronze Bomber in a doorway, Fury jokes: "Hey champ, keep going and I'll trip you over."To which Wilder responds: "How can you be so big and hide behind someone so small?"In the exchange, Wilder also compliments Fury on his weight loss, saying: "You look good bro, keep losing it."Fury recently revealed he lost over nine stone before returning from his two-and-a-half year absence from boxing.

The former world champion took a break from the sport to recover from mental health issues that followed after a suspension for an anti-doping violation.

The Gypsy King appeared on Good Morning Britain in May ahead of his first comeback fight - but says he has lost even more weight since then.

He told host Susanna Reid: "I've lost another 15lbs since we last met. So altogether, maybe about 135lbs (9.6st)."

Fair play, Tyson.

Fury will need to be at the top of his game, however, if he is to once again become champion later this year.

His opponent, Wilder, holds an unbeaten record of 40 wins and zero losses - a whopping 39 of which coming by way of knockout.

2018 has already seen some staggering blockbuster bouts in the world of boxing so far.

Fury's clash with Wilder will undoubtedly finish the year in style. It may even plant the seed for an even bigger 2019.
