Chris Froome has been consigned to hospital for a second time this year after badly cutting his thumb with a kitchen knife.
The 34-year-old Team Ineos rider said he had surgery on Friday to put the tendon in his left hand back together following the accident.
Alongside a picture of him in a hospital bed with his arm in a sling, Froome wrote the caption: "Stupidly cut my thumb with a kitchen knife and had to have surgery to put the tendon back together last night.
"Stuck giving a thumbs up for a couple of weeks. This is not my year. Can't wait for 2020."
Froome only began riding again in August after being rushed to hospital by helicopter in June following a crash during the Criterium du Dauphine.
He underwent surgery for six hours after suffering a fractured vertebrae, leg, elbow and ribs, as well as losing four pints of blood.
Froome was in hospital for over a week and was forced to miss the Tour de France.
He is targeting a return for next year's Tour, where he will be hoping to win a record-equalling fifth title.
