The injury that ruined Usain Bolt’s farewell race at the IAAF World Championships? A hamstring tear.

The 30-year-old Jamaican revealed on Thursday the details of his injury that resulted in his, and his team’s, DNF in the men’s 4x100m relay in London last weekend. He was less than halfway through his anchor leg of the one-lap relay before falling to the ground in pain. The injury was originally reported as a “hamstring cramp.” It was his final athletics race.

Bolt revealed the injury via a tweet, which was later deleted on Twitter, a platform where the eight-time Olympic champion has more than 4.8 million followers. The tweet featured a photo of Bolt’s MRI scan including a caption that read “sadly, I have tear of the proximal myotendinous junction of biceps femoris in my left hamstring with partial retraction. Three months rehab.” (You can see the deleted tweet here.)

According to USA Today, Bolt tweeted out the medical information after hearing remarks of “people questioning if I was really injured.” Canadian Andre De Grasse didn’t race at worlds because of a hamstring tear.

Earlier in the championships, held every two years, Bolt, the winner of 11 IAAF World Championships titles, won a bronze in the men’s 100m, his final individual race. He announced prior to London 2017 that he would be retiring following the Aug. 4-13 event.
