Isilon MSS Discovery Kawasaki's Michael Rutter has been declared not fit to race at round six of the Bennetts British Superbike championship this weekend at Mondello Park.

Rutter injured his left wrist after crashing out of the second race at Snetterton in Norfolk at the previous round, but raced on at the Isle of Man TT races earlier this month. It was only after the Senior race where he finished eighth, that a scan revealed that the two-time BSB runner-up had in fact broken the scaphoid bone in his wrist.

He had hoped to race and travelled to Mondello Park with his team, but after consultation with Toby Branfoot, BSB's resident doctor he and the team decided that he should not take part in the weekend's racing. Instead team-mate Stuart Easton will have a busy weekend, running in both the Superbike and Supersport classes. Rutter is hoping to be back in action in time for the Knockhill at the end of the month.

"Obviously I wanted to ride, but after seeing the X-rays, Toby advised me not to ride this weekend as I could displace the bone if I crash and that is not good!" he said, "So, the best thing to do is to get it in plaster today and leave it until Knockhill. I will be having an MRI scan next week to see if the bone needs pinning, and if it does I'll have that done on Thursday. I'm just pleased it's not my Guinness drinking wrist...The team has decided to give Stuart a run-out on the Superbikes and do the best he can. He's got a big task doing three races on Sunday, but I'm here to help him in any way I can and I think he could surprise a few people."

Easton is thrilled at the chance to ride the bigger machinery, "I'm looking forward to riding the Superbikes again, as I rode them at the North West 200. That was a different situation completely, as you ride it as fast as you dare at the North West, not as fast as you can, like you do on short circuits. I've ridden Superbikes before so I know what to expect and I know it's a one-off, so I'm just going to try and enjoy it and do my best."
