Hamstring injury puts Usain Bolt in doubt for Rio OlympicsGILBERT BELLAMY/REUTERS Usain Bolt has been diagnosed with a grade one hamstring tear. "No doubt, no doubt, no doubt," Blake said. Usain Bolt was forced to pull out of Jamaica's national championships on Friday (Saturday NZ time) with a hamstring injury just minutes before he was due to race in the 100m final. "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." Bolt has already announced that Rio will be his final Olympics.
