Jarrion Lawson, the world silver medalist in the long jump, has been provisionally suspended due to a banned substance.
Lawson was found to have epitrenbolone, according to the Athletics Integrity Unit, the IAAF’s doping watchdog. A notice of allegation was issued Aug. 3.
Lawson, 24, last competed July 22, according to Tilastopaja.org. He is ranked 16th in the world in the long jump this year.
Lawson was fourth at the Rio Olympics, where he appeared to cost himself a medal by dragging his left hand in the sand behind his landing on his final jump.
