Bolt in doubt for Rio

Sprint King Usain Bolt suffered a grade one hamstring tear during Jamaica's Olympic trials on Friday.

The six-time gold medallist revealed that he felt a twinge during opening round of the 100m and eventually withdrew from the trials altogether after he won his semi-final. 

While this means Bolt hasn't officially made the Jamaican team for Rio, luckily, the nation's selection policy allows medical exemptions, which Bolt has applied for.

The world record holder also revealed on social media that he has started treatment already and hopes to be fit for the London Anniversary Games on July 22.

In Bolt's absence, teammate Yohan Blake powered to a win in the 100m final in a time of 9.95 seconds.
