Star sprinter Hima Das on Saturday suffered a hamstring injury during the 100m heats at the ongoing National Inter-State Athletics Championships here, leaving her on the verge of missing out on the upcoming Tokyo Olympics.

Hima, who has had a lower back injury problem for a long time, did not start in the 100m final due to the injury though she qualified for it. She did complete her heat race and finished third with a timing of 12.01 seconds during the morning session.
