Kev Coghlan will join the Fuchs-Silkolene British Supersport ranks at Oulton Park after being lined up as a replacement for the injured Jack Kennedy.
Coghlan began his season racing in the Moto2 World Championship with Aeroport de Castello FTR, but a recent split with the team will see him return to the British paddock in the Supersport series.
He will join Colin Appleyard/Macadam Yamaha in place of Kennedy, who has been forced onto the sidelines following his accident at Thruxton last month.
"It is great to be getting back on a bike again and I spoke to Robin and the team about racing for them after I split with my Moto2 team and it has all come together. I enjoyed racing with them before when I did a few rounds of British Supersport and although I haven't ridden a Supersport bike since then I am looking forward to it.
“I have seen some of the races this season when I can as I have been living in Spain and with the rule changes and two races now it has been pretty exciting. I hope that we can have a good round next weekend and then go from there."
A former British 125GP racer, Coghlan made a handful of starts in the World Supersport Championship, but has raced Moto2 machinery in Spain and on the world stage most recently. He has a best finish of eighth in Moto2, achieved during this year's Spanish Grand Prix at Jerez
