Cal Crutchlow faces a race to prove his fitness ahead of the rescheduled Bennetts British Superbike Championship races at Brands Hatch this weekend after dislocating his ankle in a fall during the second race at Oulton Park.

The HM Plant Honda rider was running second behind Shane Byrne when he went down at Druids on lap 13 shortly before the race was redflagged, with Crutchlow being attended to by medics at the scene.

It capped a frustrating day for the Thruxton race winner, who had looked well set to secure a second win of the campaign when he led race one, held in tricky conditions after rain started falling just before the race was due to get underway.

However, he was caught out by the conditions at Lodge and suffered a fall into the gravel [pictured] although he rebounded to secure sixth at the finish - although it was a race that could understandably have given more.

"It was my own mistake in the first race," he said. "I was braking hard and the back-end came up and when I had both wheels on the ground the slippery conditions led to the crash. To get back on track and take sixth place and some points was something, I guess.

"I was confident of making up for it in the second race, but it was not to be. I was comfortable in second place, but then down I went at Druids. I'm not sure what happened but now I have to re-group, get some medical advice and see what we can do about the next race."

Team boss Havier Beltran admitted it had been a tough weekend for his rider, and said that the team would be seeking medical advice to ensure a speedy recovery for the youngster.

"It's been a very unfortunate weekend for Cal as he was on such good form," he said. "He was leading both races at one point but the crash in race two was nasty and he's dislocated his right ankle.

"We shall now be seeking the very best medical advice for Cal, he will undergo a scan so we can ascertain what damage has been done and then go from there."
