Sha’Carri Richardson left off US relay team, dashing last hope for Olympics

• Richardson not chosen for relay team, USTAF confirms
• American star tested positive for marijuana at US trials

Banned sprinter Sha'Carri Richardson was not on the Olympic roster released Tuesday by USA Track and Field, a decision that means the American champion's positive test for marijuana will cost her a chance at running on the relay team in Tokyo, in addition to her spot in the 100m individual race.
