Saturday’s historic all-women’s card at the O2 Arena, London, has been postponed following the death of Queen Elizabeth II. The whole card has been provisionally moved to October 15 at the same venue.

The move comes after all football fixtures in England, Scotland and Wales from the weekend were postponed.

Saturday’s show was to have been topped by the undisputed world middleweight title fight between Claressa Shields and Savannah Marshall, with the unified super-featherweight title fight between Mikaela Mayer and Alycia Baumgardner also on the same bill.

It was initially announced that the weigh-in would go ahead on Friday behind closed doors, but it was then moved back to 3pm before being cancelled.

“With respect to the country I understand that the Queen of the country passing has an entire country mourning,” Shields said on Twitter. “The government is speaking & those in higher power. Whatever the decision, I’m respectful of it.”

Bumgardner sent a message to Mayer on Twitter when the news broke, having claimed that  Mayer was struggling to make the super-featherweight limit.

“Your ass whoopin got postponed!” she wrote. “Have fun making weight again.”

News of the Queen’s declining health broke during the press conference on Thursday, with her death confirmed just hours later.

Ben Shalom, CEO of lead promoter BOXXER, said: “This is an unprecedented moment in our history and our sincere thoughts are primarily with the Royal Family and the nation at this time. Out of respect, the British Boxing Board of Control has decided to postpone Saturday’s show.

“A provisional date for Saturday, 15th October at The O2 is being worked on by all parties to stage this unique and iconic night of celebration for women’s sport at a more appropriate time.”

Adam Smith, Head of Boxing Development at Sky Sports, added: “All of our thoughts at Sky Sports Boxing are with the Royal Family at this time.

“As much as we were all looking forward to witnessing this historical sporting spectacle this weekend, it is absolutely right to respectfully reschedule the show for October 15th.”

Robert Smith, general secretary of the British Boxing Board of Control, announced that all UK shows would be postponed this weekend. 

The statement said: “The British Boxing Board of Control have decided that all tournaments this weekend will be postponed as a mark of respect to Her Majesty Queen Elizabeth II. We join as a nation in mourning and pay tribute to Her Majesty Queen Elizabeth II, honouring her dedication to our country during her long reign and the legacy she leaves behind.”
