US sprinter Richardson tests positive for cannabis; could miss Olympics

NEW YORK: American sprinter Sha'Carri Richardson has tested positive for cannabis, sources have told Reuters, and she is unlikely to get the chance to challenge for the Olympic 100 metres title in Tokyo later this month.

According to one source familiar with the matter, the positive test came at the US Olympic trials last month where Richardson established herself as a gold medal contender by winning the 100m in 10.86 seconds.

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 100m final.

Another source familiar with the matter said that Jenna Prandini, who finished fourth in the final, had already been approached to run for the US in the 100m in Tokyo.

Both sources requested anonymity due to the sensitivity of the matter.

Calls and e-mails to Richardson's agent, Renaldo Nehemiah, the US Anti-Doping Agency (USADA) and U.S.A Track and Field (USATF) went unanswered on Thursday.

In a cryptic tweet earlier in the day, Richardson wrote: "I am human".

The 21-year-old will appear on NBC's Today Show on Friday, the network confirmed to Reuters.

Richardson was billed to run in the 200m at the Stockholm Diamond League meeting in Sweden this weekend but she was not on the entry list for the race the meet's official website on Thursday. Agencies
