Yoshimura Suzuki’s James Stewart has been cleared to compete at this weekend’s Muddy Creek round of the Lucas Oil Pro Motocross Championship, series organiser MX Sports Pro Racing has revealed.

Mere days following his dominant 20th career 450 Class win at High Point, the Suzuki rider was notified that his test results from a World Anti-Doping Agency (WADA) drug test at the Seattle stop of the FIM/AMA Supercross season in April tested positive for banned substance amphetamine.

While the FIM provisionally suspended Stewart from competition at its sanctioned events, his status for the non-FIM affiliated Lucas Oil Pro Motocross Championship has been uncertain. MX Sports Pro Racing have now officially confirmed Stewart has been cleared at this point.

“The provisional suspension of James Stewart by the FIM as a result of an alleged anti-doping violation on April 12 2014, does not at this time involve MX Sports Pro Racing or the Lucas Oil Pro Motocross Championship,” a statement from MX Sports detailed.

“At this stage in the results management process, the decision to compete at a National level remains with the athlete, FIM and WADA, as MX Sports Pro Racing is not a Signatory to the WADA Code and does not have the authority to impose a provisional suspension.

“Our sanctioning body, AMA Pro Racing, has indicated that it will not restrict Stewart from competing in the upcoming Tennessee National and will reevaluate its position pending the final decision of the FIM International Disciplinary Court (CDI). If this position changes we will be notified accordingly. Until then, Mr. Stewart is free to compete without restriction.”

It was announced that Stewart had been provisionally suspended on 20 June until further notice, and he now has the right to request and attend the analysis of his B sample.

A provisional suspension imposed by the FIM does not in any way prejudge the question as to whether an anti-doping rule violation under Article 2 of the FIM Anti-Doping Code has actually been committed. This question will be addressed by the FIM International Disciplinary Court (CDI) when it adjudicates on the merits of the case.
