Former Top Gear host Richard Hammond requires knee surgery for injuries he sustained during a car crash in Switzerland.
The 47-year-old presenter was filming a segment in an electric super car for the second season of The Grand Tour series when the crash happened.
Hammond was airlifted to hospital after the accident. F1 presenter Sasha Martinego told his Twitter followers that the presenter will need knee surgery and may fly home for the procedure.

Grand Tour producer Andy Wilman gave further details of the crash, saying the presenter was seconds from being "incinerated".
"Jeremy and James both raced down to the scene of the crash as soon as it happened," he told The Sunday Mirror.
"When they saw the wreckage on fire they thought Richard was dead. It was really bad. They were staggered he had got out of it alive, because there was just nothing left."
His co-presenter Jeremy Clarkson witnessed the incident and said it was the "biggest" and "most frightening" crash he had ever seen. However, he added that "Richard seems to be mostly OK".

A statement from the Amazon series The Grand Tour said that Hammond fractured his knee in the crash but did not suffer any serious injuries.
The show's official Twitter page tweeted: "Richard Hammond was involved in a serious crash after completing the Hemburg Hill Climb in Switzerland in a Rimac Concept One, an electric super car built in Croatia, during filming for The Grand Tour Season 2 on Amazon Prime, but very fortunately suffered no serious injury."

"Richard was conscious and talking, and climbed out of the car himself before the vehicle burst into flames.
"He was flown by Air Ambulance to hospital in St Gallen to be checked over, revealing a fracture to his knee.
"Nobody else was in the car or involved in the accident, and we'd like to thank the paramedics on site for their swift response.
"The cause of the crash is unknown and is being investigated", the statement concluded.
The crash comes 11 years after Hammond suffered life-threatening head injuries following a high-speed crash as he filmed for BBC's Top Gear in 2006.
The presenter was in a coma for two weeks following the 288mph accident, but made a full recovery.
In March this year, Hammond assured fans he was fine after falling off a motorbike "many times" while filming for The Grand Tour.
Hammond was in a remote part of Mozambique in east Africa shooting the Amazon Prime show when he had the accident.
