Kirton rider Aaron Clarke had a torrid time in Scotland when he crashed twice at Knockhill, the second time in morning warm-up when he highsided at turn seven landing heavily.
He was taken to the medical centre for assessment before being sent off to hospital with a broken humerus.
Clarke was doing well in free practice but suffered a small crash in the first qualifying session where he lost the front going into turn two.
He thought the bike was ok and had just some minor cosmetic damage but when he went out in the second session he discovered there was a mechanical fault which hampered his progress.
But he battled on and made it onto the grid by the skin of his teeth, securing the final place on the grid for the start of the race.
But after just three laps of the short session he highsided going into turn seven knocking himself out and injuring his arm which put paid to his aspirations for the race.
Clarke will have an operation to pin his broken arm this week.
