Manx Grand Prix organisers say a racer has now had a positive result for a recreational drug following testing.
Alex Sinclair was axed from this year's racing after ACU Racing said he'd had a "not-negative" result.
But the organisation now says it's had confirmation of the result following a lab analysis.
The ACU says it'll now consider his case - racers found to be doping can be banned for a minimum of two years.
