DALLAS - UPDATE 7/2: Sha'Carri Richardson officially suspended, will miss Olympic 100 after drug test
----------
Track and field star and Dallas native Sha'Carri Richardson could be suspended from the Olympics after failing a drug test.
The sprinter confirmed she tested positive marijuana, not performance-enhancing drugs.
The failed drug test could still mean a 30-day suspension that would make her miss the women’s 100-meter race in Tokyo.
She may be eligible for a relay that would happen after 30 days.
Thursday afternoon, Richardson cryptically tweeted: "I am human."
She told NBC it was after her biological mother died, even though she knew it was banned.
The 21-year-old Dallas Carter High graduate said she will take responsibility for her actions that could cost her a chance to compete and millions in endorsements.
Reuters reported Richardson was off the roster for a competition this weekend.
Richardson qualified for the Olympics with a standout performance at the United States trials in Oregon late last month.
