Clarke Could Miss Silverstone

Clarke, driving for the Raikkonen Robertson Racing team, took advantage of the five-week break in the Championship to attend the Rip Curl Boardmasters evet at Fistral Beach, Newquay. But the young Briton hurt his knee while surfing on Thursday and reported to be in discomfort since.

"I'm not sure how it happened, but as I went to stand up on the board I felt a shooting pain in my right knee," Clarke recapped. "It went away almost as quickly as it had come, but it really hurt at the time and was aching again on Friday morning. I can feel it when I apply pressure to the pedal when driving, so I'm hoping it's nothing serious."

Clarke is set to see a medical specialist on Tuesday to determine the seriousness of his injury, and he added: "I've invited a number of the guys from Newquay to join us next weekend, so I'd be gutted if I had to miss the race through injury.

"We'll just have to see how it goes over the next few days."
