The TV star was knocked out in his second horror crash while filming.
The Grand Tour star hit his head coming off a motorbike in a remote part of Africa.
Richard almost died in a 288mph collision on Top Gear 11 years ago.
Hammond’s co-star Jeremy Clarkson said of his pal’s horror motorbike crash: “He really did hurt himself quite badly.”
The Hamster, 47, was knocked out after falling from the bike and hitting his head.
He lay unconscious in the road in remote Mozambique, miles from medical help.
But asked if his friend went to hospital, Clarkson quipped: “We don’t do hospitals.”
Crew on TV’s The Grand Tour raced to Richard’s aid, mindful he suffered serious brain damage in a 288mph smash 11 years ago. It is not known if he was wearing a helmet in the latest drama.
A show source said: “Richard was travelling quite fast when he came off. It caused instant horror on set.
“There was a lot of concern.
“If his injuries had been serious it wouldn’t have been easy to get medical attention.
“It’s very remote there and facilities are basic.”
Clarkson, 57, and co-star James May, 54, joined the show’s medic at the scene.
The source added: “The lads are known for having a laugh on set but Richard’s previous accident is fresh in their minds. They were all shaken by the latest incident.
“But now they know Richard is fine they are back to jokes and banter.”
The accident is still expected to feature in the second series of the Amazon Prime motoring show later this year.
The trio flew to Mozambique a fortnight ago. A third of the population in the African nation are unable to access health services.
Dad-of-two Richard was in a coma for two weeks in 2006 after a jet-powered car he was piloting for Top Gear crashed at 288mph.
Its right tyre blew as he tried to set a land speed record at RAF Elvington near York.
He was airlifted to hospital in Leeds. Richard later revealed he suffered depression, paranoia and memory loss due to brain damage.
