Jamaican sprinter Yohan Blake will miss the rest of the 2014 season after undergoing surgery on an injured hamstring.
The 24-year-old suffered the injury in the Glasgow leg of the Diamond League earlier in the month, pulling up during the 100 metre race.
The athlete left the stadium in a wheelchair, and has now been ruled out for the rest of the season.
Blake took to Facebook to give his thoughts on the news, writing: "Guys. I am down but just a little.
"I'm still going to fight even harder for everyone who continues to support me. I feel I owe it to the sport and the fans. Thanks for all the good wishes. It really means a lot."
The 2011 world champion, who is also the second fastest man in history, had a series of hamstring issues last year, too, forcing him to miss the chance to defend his title from Daegu.
With 2015 another World Championship year, 'The Beast' will be hoping this is the last of his injury problems. After all, it is Blake who has looked the most likely to take the crown from his teammate, Usain Bolt's, throne.
