Former Australian motocross champion and international Jake Moss has been handed a four-year sanction that will see him not eligible to compete in the sport until 14 July 2020 after violating the Motorcycling Australia (MA) Anti-Doping Policy.

According to a statement released by MA, 28-year-old Moss had violations of Articles 2.1 and 2.2 of the policy ‘for the presence of prohibited substances in an athlete’s sample and the use of a prohibited substance’.

Moss tested positive to Ostarine (Class S.1.2 Other Anabolic Agents) on 22 May at Murray Bridge in South Australia during round four of the 2016 MX Nationals. Testing was conducted by Australian Sports Anti-doping Authority (ASADA).

Today’s statement confirmed Moss ‘did not apply for a hearing in the Court of Arbitration for Sport and accordingly the mandatory four-year sanction has been imposed’. The provisional suspension by MA was imposed on 15 July and his sanction has been backdated to include that period.

MA’s statement said Moss is now ineligible to participate, as an athlete or support person (including coaching or officiating), until he has completed his four-year sanction and the ban includes using member facilities. Moss resigned from his factory Kawasaki contract in August and has since retired from motocross.

There has been no official update in regards to Jake’s twin brother Matt Moss, the multi-time national champion who has also been provisionally suspended from competition due to a potential anti-doping rule violation.
