Gearlink Kawasaki’s Alastair Seeley received a ten-second penalty following a collision with Jason O’Halloran in the second British Supersport race at Silverstone on Sunday.
There was contact between Seeley and the Samsung Honda rider on lap 11, with O’Halloran crashing out while the Ulster star went on to finish on the podium in third.
However, following an investigation into the incident, Seeley was handed a time penalty of 10 seconds by the organisers, bumping him seven places down the results sheet to tenth position.
The ruling means Mar-Train Racing’s Stuart Easton now holds an advantage of 19 points over Seeley ahead of the final round at Brands Hatch on October 20.
Scottish rider Easton dramatically crashed out on the opening lap of Saturday’s race, with Seeley capitalising on his rival’s misfortune as he battled to a gritty race victory to secure 25 points.
Easton was forced to start from the fourth row of the grid in the second race at the Northamptonshire circuit yesterday but charged through the pack, eventually finishing fourth with Luke Mossey taking the win from Billy McConnell and Seeley in third after a breath-taking race.
Speaking before the decision was announced, Carrick man Seeley - who celebrated his 34th birthday at Silverstone - said: “I went into the hairpin and showed a wheel as it’s a good passing place. Jason sort of lay on me to not give me the place and there was contact.
“Unfortunately he went down but rubbing’s racing and everyone knows that,” he added.
“We worked hard in that race and it was a pity the Safety Car came out because I was pulling Jason [O’Halloran] in a bit, but it is what it is and it’s nice to be back on the podium again, plus we’ve clawed back more points on Stuart.”
Glenn Irwin was seventh in race two with Marshall Neill 11th on the Wilson Craig Honda.
Nikki Coates was 17th with Paul Jordan finishing 23rd.
