Doping is a serious offense in any sport. James Stewart was suspended by the World Anti Doping Agency (WADA) for 18 months when WADA found amphetamines in Stewart’s test sample. Stewart later said that it was from Adderall, but since Stewart had not disclosed he was using Adderall to WADA (and not telling WADA what drugs you are using or getting an exemption for their use is a serious violation of the rules). While Stewart said that his Adderall was prescribed by his doctor, Adderall can be used as a cover for other drugs—and WADA never said what amphetamine-based drug was actually found.
Now, the Australian Nationals may have a drug controversy on their hands and they may not. But, they certainly have a mystery. We don’t want to get into the rumor business, but suffice it to say that the Moss brothers, Jake and Matt, were pulled from the seventh round of the Australian Nationals by their Kawasaki sponsors for undisclosed reasons.
Kawasaki released a short statement on the matter: “Kawasaki Motors Australia can confirm Matt Moss and Jake Moss were absent from the Conondale round of the 2016 MX Nationals on Sunday, 17 July, due to sporting disciplinary circumstances still currently under investigation. Further information will be released in due course.”
If you remember the Stewart penalty, it is a long drawn out affair, that involves a retest of the B sample, a hearing, an appeal and eventually a penalty. It took the AMA and WADA eight months to get around to suspending Stewart. Matt Moss sits fifth in the 450 overall championship at 381 points. His brother Jake Moss is 12th in the 250 Championship with 278 points. Their teammate, Kade Mosig was not involved in Kawasaki’s actions and is fourth in the 450 championship at 381 points too.
