Queensberry Promotions has announced four more summer shows including the returns of the highly-touted Daniel Dubois and heavyweight rival Joe Joyce.

Dubois (14-0, 13 KO’s) faces Russian-born Erik Pfeifer (7-0, 5 KOs) on August 29 in a defence of his WBO International heavyweight title as he tunes up for his grudge match with Joyce at the O2 Arena on October 24.

Pfeifer, who campaigns in Germany, is a two-time Olympian, having competed at the 2012 and 2016 Games and previously won bronze medals at the 2011 and 2013 World Championships.

On July 25, Joyce (10-0, 9 KOs) will make his summer return against German heavyweight Michael Wallisch (20-3, 13 KOs) in a scheduled 10-rounder. Wallisch has previously been stopped by Tony Yoka, Efe Ajagba and Christian Hammer.

In the other two main events, Commonwealth light-heavyweight champ Lyndon Arthur (16-0, 12 KOs) faces Dec Spelman (16-3, 8 KOs) on July 31 while WBO European 130lbs title-holder Archie Sharp (18-0, 9 KOs) meets Jeff Ofori (10-2-1, 3 KOs) on August 20.

The originally announced fights of Anthony Cacace vs Lyon Woodstock and Lerrone Richards vs Umar Sadiq have been postponed to a later date.

“I’m delighted to be able to give fans more clarity as to what they can expect from the huge Summer of boxing on BT Sport,” said promoter Frank Warren. “Everyone at Queensberry and BT have worked hard to get these shows up and running and I believe this schedule is second-to-none in the boxing world right now.

“Daniel and Joe returning is obviously huge, headline news and scheduling these fights reflect our growing confidence that Daniel and Joe will be able to finally square off on October 24. I spoke to both teams and they both said that as it looks like we’re going to finally do this in October, they’d like tune-up fights first. Thankfully, BT liked the idea and here we are.

“Daniel hasn’t boxed since December and Joe will have been out for an over year. These fights will sharpen them up and I’m sure they will deliver knockout performances that will get fans even more excited for October. For Erik and Michael it’s a chance to cause huge upsets.

“That’s five huge dates locked in now, where Queensberry and BT will set the standard for Boxing in this new era,” he continued. “Fans can sit back and enjoy huge British battles and big, big names all live on BT Sport.

“As the rest of the country gets back to work, so does British boxing and I’m delighted that it’s Queensberry Promotions leading the charge.

“Originally, Anthony Cacace was due to fight Lyon Woodstock on our second show, but Anthony has a slight dental issue he needs to take care of. That fight is still signed, it’ll just happen a little later than we anticipated. Fans can still look forward to that fight later this year.

“The same is true for Lerrone Richards vs Umar Sadiq. That fight is signed, but Lerrone has a personal issue which means we’ll have to come back to it a little later than we’d like. But if you look at the fights we’re offering, I don’t think there’s a fan alive who can feel hard done by.”
