KINGSTON (Reuters) - 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 U.S. Olympic trials last month where Richardson established herself as a gold medal contender by winning the 100m in 10.86 seconds.
