Jarrion Lawson, the world silver medalist in the long jump, has been provisionally suspended after testing positive for a banned substance June 2.
Lawson failed a drug test for epitrenbolone, a metabolite of the banned anabolic steroid trenbolone. He was informed Aug. 3, according to the Athletics Integrity Unit, the IAAF’s doping watchdog.
“Having now researched trenbolone, we have discovered that it is a USDA approved steroid, legally used in the United States in the production of beef,” Lawson said in a statement, according to his agent. “Lab results have shown that there were extremely trace amounts of the metabolite in my sample.
