Karl Harris will not participate in the final British Superbike Championship round of the season at Oulton Park having been diagnosed with concussion following his race one accident.
Harris was battling for the lead of the race as the riders rounded Island bend on lap three, but was caught on the outside of Tommy Hill heading into the Shell hairpin, Harris having no choice but to run off the circuit.
With his SMT Honda digging into the ground, both rider and bike were flung into the gravel trap, Harris making heavy contact with the barrier.
Forcing the race to be stopped, Harris was taken to Leighton hospital for further assessment, where he was diagnosed with concussion and sore back. There was no evidence of any serious injuries, however.
Harris had been a star performer over the weekend, topping free practice before qualifying in third position for the three races.
