Bolt delivers injury details

LONDON - Usain Bolt on Thursday delivered a rebuke to critics who questioned whether he really sustained an injury in his farewell race at last week's World Athletics Championships by revealing details of his hamstring tear.

The Jamaican sprinter, stung by speculation that he pulled up in the anchor leg of the 4x100m relay final in London last Saturday because he was too far behind to win, said the injury will require three months of rehabilitation.

The eight-time Olympic gold medalist was also adamant in social media posts that he never cheated his fans.
