Sir Bradley Wiggins faces a spell on the sidelines after pulling out of Channel 4 extreme sports show The Jump due to a broken leg.

Wiggins, Britain’s most decorated Olympian with eight medals,  suffered a small fracture to his leg during training this week.

The 36-year-old was taking part in the show as a new challenge after announcing his retirement from cycling at the end of last year.

In his final race on British soil, Wiggins came second with Mark Cavendish in the Six Day Series in London in October, when the British pair were edged out by Belgian duor Kenny De Ketele and Moreno De Pauw.

But the former Tour de France champion has had to cut short his efforts on the show and broke the news of his withdrawal on Twitter by posting: “Gutted to be leaving The Jump. I wanted to give you an injury update.

"Seen a specialist, I have a small leg fracture and need to rest for 3-6 weeks. Good news no surgery or cast required.

"Huge thanks to the crew and good luck to all of the cast. Due to the way the show is filmed, I'll still be on until show four, so tune in.

"No horror smash, small training injury which means I can't compete. No terrible break, no cast, just need to rest it."
