After testing positive for a prohibited substance, Olympic silver medalist Chris Creveling has been banned from competition for four years and will miss the 2018 PyeongChang Olympics.
On Oct. 18, 2016, an out-of-competition urine test showed clomiphene in Creveling’s system. The drug is classified by the US Anti-Doping Agency as performance-enhancing for its effect on testosterone levels. It’s most commonly taken by women who don’t ovulate to treat infertility.
His four-year ban is effective from Nov. 18, 2016, when Creveling, 30, accepted a provisional suspension.
Creveling and the U.S. men, including J.R. Celski, won a silver medal in the 5000m relay at the 2014 Sochi Olympics.
