'While rehearsing for the premiere of Dancing with the Stars, Christie Brinkley suffered injuries which required surgery to her wrist and arm,' the release said.

'She is unable to continue her planned participation on the show. Keeping it all in the family, her daughter Sailor Brinkley-Cook, a Sports Illustrated model, has chosen to quickly step in with hours to learn the entire routine and will compete in her mother's place for the remainder of the season. 

'We wish Christie a full and speedy recovery and look forward to seeing her in the audience, whenever possible, proudly supporting Sailor.' 

The bombshell was all set to debut on season 28 of Dancing with the Stars on Monday.

But now she will have to sit it out in the audience with her daughter Alexa Ray Joel as they watch Sailor try the Samba.
