TOKYO 2020: Richardson tests positive for Cannabis
American sprinter Sha'Carri Richardson may not run in the Olympic 100-meter dash this summer after testing positive for marijuana.
Richardson had been tipped to challenge for the gold medal after winning the 100 meters dash at the US Olympic trials in 10.86 seconds. However, the tests conducted at the events confirmed that she had used cannabis.
A positive test during the trials would mean all of Richardson's results from the meet would be wiped out, voiding her victory in the 100-meter final.
Unnamed sources also told Reuters that Jenna Prandini, who finished fourth in the final, had already been approached to run for the U.S. in the 100 meters in Tokyo. Both sources requested anonymity to Reuters due to the sensitivity of the matter.
Cannabis is banned by the World Anti-Doping Agency (WADA), but if athletes can prove that their ingestion of the substance was unrelated to sports performance then a suspension of three months rather than the usual four years is imposed.
Richardson was billed to run in the 200 meters at the Stockholm Diamond League meeting in Sweden this weekend but she was not on the entry list for the meet's official website on Thursday.
She is hoping to become the first American woman to win the Olympic 100-meter title since Gail Devers in 1996 after posting 10.72 seconds in April -- one of her five runs under 11 seconds this season.
Calls and e-mails by Reuters to Richardson's agent, Renaldo Nehemiah, the U.S. Anti-Doping Agency (USADA) and U.S.A Track and Field (USATF) went unanswered on Thursday. The 21-year-old will appear on NBC's "Today Show" on Friday, the network confirmed.
