American sprinter Sha'Carri Richardson, expected to be one of the biggest draws at the Tokyo Olympics, will miss the 100 meters at the games after accepting a one-month ban for testing positive for cannabis during her U.S. trials victory in June.
The United States Anti-Doping Agency (USADA) confirmed the suspension on Friday, though the 21-year-old still has a chance of running in the Olympic relay events.
The positive test came at the U.S. Olympic trials when Richardson underlined her credentials as a serious gold medal contender by winning the 100m in 10.86 seconds.
