Northern Ireland rider Alastair Seeley was left seething after being taken out while leading Monday's British Superstock Race 1 at Oulton Park.
Seeley was carried onto the gravel by Alex Olsen as the pair diced for the lead on lap 11 of the 14-lap contest.
Olsen attempted a daring move up the inside of Seeley at Lodge corner before clipping the rear end of the Carrick man's bike, forcing both riders off the track.
