MGP rider previously returned 'non-negative' reading and was excluded from event
Manx Grand Prix competitor Alex Sinclair has now been confirmed to have returned a positive test for a 'recreational drug' at this year's races.
Race officials say the latest development comes after 'confirmatory analysis at an accredited laboratory'.
The MGP competitor was excluded from this year's event with immediate effect last Tuesday (20 August) after initially returning a 'non-negative' result during a random screening.
ACU Events Ltd adds 'the quantitative result of the confirmatory analysis is consistent with the misuse of a controlled drug.'
The matter is now with the Auto-Cycle Union - sanctions for competitors caught doping can be a ban from ACU competitions for a minimum of two years.
