Australian motorcyclist Matt Moss has been hit with a four-year ban for testing positive for Ostarine, according to RacerXOnline.
Ostarine is a drug that mimics the effects of anabolic steroids, and governing body Motorcycling Australia announced the decision on Tuesday. The Australian Sports Anti-Doping Authority approved the ban, so Moss can't compete in any sport that is under the World Anti-Doping Agency anti-drug policy until July 15, 2020.
Moss took and failed the drug test on May 22, 2016, so the ban begins from July 15, 2016.
Matt's twin brother, Jake, was suspended for violating the same rule, and he is also banned until July 15, 2020.

Matt Moss won the premier class championships in back-to-back years in 2013 and 2014 in the Australian MX Nationals, and he also won Australian Supercross championships in those years.
He was also on Australia's team that made the podium at the Motorcross of Nations, which is the only time Team Australia has ever made the podium.
Moss has also competed in the United States, though his last appearance came in 2014.
It's unclear whether Moss will have the desire to race again once his ban is lifted in 2020, or if a team will have the desire to sign him once he is eligible to return.
