Britain's four-time Tour de France champion, 34, suffered a fractured right femur, a broken hip, a fractured elbow and fractured ribs and lost consciousness following the crash.

Froome is awake and doctors are "very happy with his progress".

Team Ineos said he will remain in hospital for the next few days.

The crash occurred during a practice ride before stage four of the Criterium du Dauphine in Roanne, France.

Froome took his hand off his handlebars to blow his nose and was travelling at 54km/h when a gust of wind caught his front wheel, causing him to hit a wall.

He was airlifted to St Etienne Hospital for surgery.

"First things first, the surgery was a success," said team doctor Richard Usher. "The operation, which lasted for six hours, went very well.

"Chris woke up this morning and was reviewed by the intensive care consultants and the orthopaedic specialist who operated on him and they're both very happy with his progress to date.

"Chris will remain in hospital for the next few days for observation, but he is already actively engaging in discussing his rehabilitation options, which is very encouraging."

Chief surgeon Remi Philippot told AFP that Froome faces a "long recovery".

"The surgery was carried out as a semi-emergency to try to avoid any early complications that can develop from that sort of trauma," he said.

"Now recovery is going to be long. Roughly speaking, you are looking at a minimum of six months out of competition.

"The objective is not just about getting back on the bike, but on rehabilitating himself for the future.

"On a sporting level, he will need to make an exceptional recovery with the mental capacity required to recover and then get fit again."

Meanwhile, cycling's governing body the UCI has announced that 2011 Vuelta a Espana champion Juan Jose Cobo had been found guilty of an anti-doping violation.

That could see Froome, who finished second in the race, retrospectively awarded the victory.
