Six-time Olympic gold medalist Usain Bolt has suffered an injury ahead of Rio after tearing a hamstring at Jamaica's Olympic trials.
Bolt, 29, sustained the grade-one tear during the first round of the 100m and withdrew after winning his semi-final.
He is still expected to defend his 100 and 200m titles as Jamaica's selection policy allows medical exemptions.
Statement from Usain Bolt:
“After feeling discomfort in my hamstring after the first round last night and then again in the semi-final tonight I was examined by the Chief Doctor of the National Championships and diagnosed with a Grade 1 tear. I have submitted a medical exemption to be excused from the 100m final and the remainder of the National Championships. I will seek treatment immediately and hope to show fitness at the London Anniversary Games on July 22 to earn selection for the Olympic Games in Rio”.
