Carl Froch has been forced to miss training for reality TV show Tumble after coming down with a bout of food poisoning.
The boxer is one of a number of celebrities taking part in the show, which gets underway on Saturday.
A source told The Sun: "Carl has been eating lots of chicken as he's bulking up on protein to make sure he's as strong as possible.
"But a dodgy batch has really knocked him off his feet and made him miss a lot of training. Carl takes his training really seriously and was devastated that he couldn't carry on.
"But a lot of the training has been four metres off the ground in a hoop, and that's not easy when you're queasy. The show starts in just a few days' time so Carl is desperate to get fit and up to speed."
The show will see celebrities compete by performing gymnastic routines with professional gymnasts and acrobats.
