US sprinter Sha'Carri Richardson questioned why Russian figure skater Kamila Valieva was allowed to continue competing at the Beijing Games amid a doping charge, months after a positive test for cannabis derailed her own Olympic dreams.
The 21-year-old American was expected to be one of the biggest draws at the Tokyo Summer Games after winning the 100 metres at the US trials, but was barred from competing after accepting a one-month ban for her positive test for cannabis.
She later said her action was the result of mourning the death of her mother, as the incident rekindled the debate over the use of cannabis among athletes.
"Can we get a solid answer on the difference of (Valieva's) situation and mines?" Richardson Tweeted. "My mother died and I can't run and was also favoured to place top 3. The only difference I see is I'm a black young lady."
Her agent could not be reached for further comment.
Sport's highest court on Monday cleared the 15-year-old Russian Olympic Committee's Valieva to continue competing in Beijing, although no Olympic medals will be awarded at the women's singles event on Thursday if she finishes in the top three.
