Cal Crutchlow has undergone successful surgery on the broken left collarbone he sustained during qualifying for last weekend's British Grand Prix - but the Monster Yamaha Tech 3 star has admitted that the injury is 'a lot worse' than that similarly suffered by team-mate Colin Edwards only a week earlier.

Having looked in good shape to give his home supporters something to cheer about at Silverstone, Crutchlow fell at high-speed early on in qualifying, breaking his left collarbone in five places. Surgery was delayed whilst the MotoGP rookie was assessed for a neck injury suffered in the crash.

Initial checks at the John Radcliffe Hospital in Oxford showed a suspected non-displacement fracture of his C2 vertebrae, but subsequent CAT scans happily revealed no damage to his neck, and the 25-year-old was immediately transferred to the Royal Derby Hospital for surgery on his left collarbone, having a titanium plate and several screws inserted in his shoulder in an operation carried out by specialist surgeon Dr. David Clark.

The former World Supersport Champion has already begun the process of rehabilitation with intensive physiotherapy, but it is too early to know whether he will be fit to participate in the Dutch Grand Prix at Assen next weekend. Further information is expected in the next few days.

"The operation on my collarbone was a success and the doctors seem really happy with the outcome," he said, before cautioning, "but I am still in a lot of pain. Unfortunately, the break is a lot worse than the one Colin had in Catalunya, and I've got different pain and movement levels. I've also spent two days lying on my back with a suspected neck injury, so my shoulder just got swollen.

"I am not very happy that this happened to me [ahead of] my home race at Silverstone when things were going really well for the weekend. I don't know if I will ride at Assen. We will have to wait and see, but I'll be trying 100 per cent to be there if I can."

After being forced to miss the Catalan outing on the calendar, interrupting his hitherto unbroken run of 141 race starts in the premier class, Edwards returned at Silverstone where he took a popular podium finish - inspiration, if ever it were needed, for Crutchlow to make a speedy recovery of his own.
