American sprinter Sha’Carri Richardson has tested positive for cannabis, and she is unlikely to get the chance to challenge for the Olympic 100m title in Tokyo later this month.
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 10.86sec.
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.
