Derek Chisora and Deontay Wilder are set to go head-to-head in a heavyweight fight at London's O2 Arena

DAZN have been forced to apologise during their live coverage of the undercard of Saturday's fight between Derek Chisora and Deontay Wilder. The broadcaster issued their apology during the fight between Ashton Sylve and Raul Antonio Galaviz Hernandez.

A message at the top of the screen said: "Sorry, we temporarily lost sound. It'll be back as soon as possible".

Saturday's heavyweight fight at the O2 Arena in London sees Chisora return to the ring for the first time in over a year. His last fight was a unanimous decision win over Otto Wallin in February 2025.

The Brit takes on America's Wilder, who has won just two of his last six fights and comes into the contest on the back of a knockout win over Tyrrell Anthony Herndon.

Chisora tipped the scales going into Saturday's fight at a career-high weight at 19st 1lbs while Wilder weighed in at 16st 2lbs.

Speaking after the main broadcast on DAZN had begun, presenter Ade Oladipo said: "I did hear there were a few gremlins with the sound a bit earlier for those of you that are watching it on YouTube.

"Those gremlins have now gone, so make sure you buy the pay-per-view."

The fight has been dubbed one of the last of both men's careers. Chisora, 42, has already promised that he will hang up his gloves following the bout on Saturday and hopes to pick up one last win over the American.

Speaking to DAZN ahead of the fight, he said: "I know he has PTSD with Tyson Fury. That's the game of boxing, mind games.

"All of you know what time it is. When I strap up the boots and gloves I go in there, there's only one thing, let's go. There's no point sugar-coating it, I know it will be an amazing amazing fight for me and this man here.

"I don't look at those fights with Zhang and everybody, I look at this man now, he says he's healed, he's trained well, I'm excited."

Wilder, meanwhile, has addressed suggestions that there had been a problem surrounding the gloves heading into the fight, admitting the issue had been on his side.

The 40-year-old said: "I broke my hands so many times, I just want to be comfortable in the ring, I had the issue with the gloves being too tight on my hands but we'll get it straightened out.

"I'm a true fighter, when it's time to fight let's go, I love fighting just like this man loves fighting. All my life I've had to fight.

"Come Saturday night they'll get an explosion."
