Stuart Easton says he is 'doing all he can' to be in shape for the sixth round of the MCE British Superbike Championship at Oulton Park after being forced to skip his home Knockhill event.

Easton, who has performed well on his return to competition having been forced to sit out much of 2011 with a series of injuries sustained at the North West 200, underwent an operation to have metalwork removed from his leg, thus forcing him to skip Knockhill.

However, while the operation was a success, Easton says he is now having problems with the knee he twisted in an accident during the non-championship British Grand Prix supporting Silverstone 200 race.

As such, though Easton is certainly not ruling out competing at Oulton Park this weekend, the Rapid Solicitors Kawasaki rider is facing a race against time to be in optimum shape.

"It's been a tough couple of weeks and I'm doing all I can to try and get fit for this weekend as I can't afford to miss out on points for another meeting. It's very frustrating because the operation went fine and my leg is OK, it's the knee I twisted in my crash at Silverstone which I'm having trouble with.

"I'm having physiotherapy three times a day and hopefully I'll be able to ride on Friday as I really enjoy Oulton Park and got a good result there earlier in the year."

Another skipped meeting would prove detrimental to Easton's title aspirations, the Scot already dropping out of the provisional top six after Knockhill and poised to be demoted by close-following rivals if he doesn't score points.
