1st July 2016 – Statement from Usain “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”.
