The entertainer had been due to make his big TV comeback as a contestant on the ITV skating show in the new year, but has injured himself during training.
He will be replaced on the line-up by former Blue Peter presenter Radzi Chinyanganya.
In a statement, Michael said: “Shortly after shooting the Dancing On Ice Christmas Special I took a tumble whilst rehearsing for the January shows. After the fall, I thought I had sprained my wrist but it turns out that it is broken.”

He continued: “Unfortunately, the medics have told me that I cannot compete. I am absolutely devastated; I have loved every second of the journey so far with my wonderful dance partner Alex Murphy and the support from the public has been overwhelming.
“I have been fortunate enough to work with such a great bunch of people over the previous few months; trainers, celebrities, pro skaters, the judges, Holly and Phil and the incredible production team at ITV who really are exceptional and help to make it the fantastic show that it is.
“I shall be in the studio for the first show on Sunday 5 January and hope to make other appearances throughout. I would like to wish the whole of Dancing On Ice 2020 the best of luck.”

Radzi also said: “I am thrilled and privileged to be part of the Dancing On Ice 2020 cast. I am absolutely gutted for Michael, who is one of my all-time favourite TV presenters, and I wish him a speedy recovery.
“I’ve only got two weeks to get ready to ice skate in front of the nation so I’m looking forward to a Christmas and New Year filled with training on the ice!”
