Bolt tweeted an image of his muscle tear and said the injury will require three months of rehabilitation.
He could only manage bronze in his penultimate race – the men’s 100m at London 2017 – before pulling up injured just as he began to hit top speed in his final event, the 4x100m relay, last Saturday.
It meant the 19-time global champion, recently described by Lord Coe, the president of athletics’ governing body the IAAF, as “a genius” akin to boxing legend Muhammad Ali, bowed out being helped off the track by his team-mates, barely able to stand upright.
“Sadly I have a tear of the proximal myotendinous junction of biceps femoris in my left hamstring with partial retraction. Three months rehab,” the eight-time Olympic champion posted on Twitter along with an x-ray of his leg, the first of four messages which were all subsequently deleted.
“I don’t usually release my medical report to the public but sadly I have sat and listened to people questioning if I was really injured,” Bolt said on social media, before later deleting the posts.
“I have never been one to cheat my fans in any way and my entire desire at the championship was run one last time for my fans.”
“Thanks for the continued to support my fans and I rest, heal and move onto the next chapter of my life.”
