MotoGP rookie Cal Crutchlow spent a 'comfortable' night in Oxford's John Radcliffe Hospital after breaking his left collarbone in a high-speed fall at the start of Saturday's qualifying session for the British Grand Prix.

Crutchlow's collarbone, which is broken in three places, will require surgery, but no decision has been taken on whether he will remain in Oxford or be transferred to Manchester to see a specialist who has treated the 25-year-old for a previous shoulder injury.

The Monster Yamaha Tech 3 rider is also being assessed for a neck injury. Writing on his Twitter account (@calcrutchlow) Crutchlow said:

"Tweeting from my hospital bed! Just to say thanks so much for everyone's support...! I am so sorry for everyone that turned up this weekend bought a flag, hat, or tshirt to wave.

"I crashed with no heat in rear tyre, same as Vale last year, Colin last week. It happens to the best of them.

"My collarbone is in 3 pieces and I have MRI on neck as the docs think it's broke, but I am fine! I appreciate all the support.

"I was confident for the weekend too. It will take some getting back from this injury but I will be back... I have no doubt better than before.

"On a cool note I was so smashed on gas and air yesterday nothing hurt until today!"

With Crutchlow in hospital, Tech 3 team-mates Colin Edwards - who broke his collarbone just nine days earlier in Catalunya - and Bradley Smith raised spirits with shock podium finishes in the MotoGP and Moto2 races respectively.

"We can't be completely happy [today] because of what happened to Cal and it was a big pity he couldn't race, but he is a fighter and we'll see him back stronger than ever soon," said team manager Herve Poncharal.

"I know how much he wanted to ride in front of his home crowd, but he has seen what Colin has achieved so quickly after his collarbone injury, so hopefully this will be a good inspiration for him."

Edwards, who also had surgery for his collarbone injury, commented: "Nobody wants to get hurt, but being injured for your home race is really tough to take, so I wish Cal a quick recovery and hope to see him back in Assen."

Crutchlow - a best of sixth in qualifying and seventh in the races held so far this season - had been inside the top six in all three free-practice sessions at Silverstone.

The Dutch TT at Assen takes place on June 25.
