Jamaica's world champion Shericka Jackson (30) withdrew from the 200 metres at the Paris Olympics on Sunday, less than a month after she suffered an injury at a tune-up meet in Hungary.
Jackson did not run the 100 metres in Paris saying her injury played a part in her decision.
Jackson's withdrawal comes a day after Jamaica's three-time Olympic champion Shelly-Anne Fraser-Pryce pulled out of the women's 100m with an injury.
At last year's world championship in Budapest, Jackson clocked a scorching 21.41 to capture her second consecutive world title in the distance and narrowly missed breaking the world record of 21.34 set by the late Florence Griffith-Joyner in 1988.
But Jackson, who has never won an individual Olympic gold medal, has not been at her best this season, clocking times about a second slower than her world championship run.
