LONDON -- Canadian sprinter Andre De Grasse will miss the upcoming world championships due to a torn hamstring.

De Grasse suffered the injury on Monday during a training session. In a release, Athletics Canada said that a second opinion on Wednesday confirmed the diagnosis.

"Injuries are a part of the sport, and the timing of this one is especially unfortunate," De Grasse said in a statement on his Facebook page. "While I'm in the best shape of my life and extremely disappointed that I will not have the chance to compete for my country in London, I can't forget or be ungrateful for the successes that I've been blessed with up to this point in my career."

De Grasse adds: "I'll be back stronger and faster than ever."

The injury is a big blow to the Canadian team who was relying on De Grasse for medals at the worlds. He was a medal threat in both the 100 and 200 metres and also served as the anchor on Canada's 4x100 relay team.

The 22-year-old from Markham, Ont., was due to race against Usain Bolt in the 100 metre final at London Olympic Stadium. Bolt, an 11-time world champion, plans to retire after the race. De Grasse was supposed to open the worlds with the 100 heats on Friday before the final on Saturday.

"I really feel for Andre, I know he really wanted to make a mark here at the world championships," Athletics Canada head coach Glenroy Gilbert said in a statement. "Injuries are part of the sport, obviously, the timing is terrible.

"As a team the focus doesn't change, we need to be ready to compete starting Friday. We've been talking about the depth of the program, now is a chance for some of our other stars to shine, and have some of our up and coming athletes step up."

De Grasse has had a strong season in the Diamond League and was atop the standings in both the 100 and 200 events.

De Grasse won bronze in the 100, silver in the 200 and bronze in the 4x100-metres relay at last summer's Rio Olympics. He won bronze at the 2015 worlds in the 100 metres while also capturing a bronze with the 4x100-metres relay team.
