LONDON - Canadian diver Alexandre Despatie won't be adding to his Olympic medal collection in the three-metre synchronized event.

Despatie and Reuben Ross finished sixth at the London Olympics, six weeks after Despatie had a diving accident that left his Olympics in doubt.

Qin Kai and Luo Yutong captured China's fourth diving gold medal of the Games, scoring 477.00 points.

Russians Ilya Zaharov and Evgeny Kuznetsov won the silver with a score of 459.63, while Americans Kristian Ipsen and Troy Dumais took the bronze with 446.70.

Despatie of Laval, Que., and Ross, from Regina, bronze medallists at the world championships in 2009 and at the World Cup in London earlier this year, scored 421.83 points.

The 27-year-old Despatie, a three-time world champion and two-time Olympic silver medallist, is competing in his fourth Olympics just six weeks after suffering a concussion when he smashed his forehead on the springboard at a practice in Madrid. The accident left a 10-centimetre gash along his hairline that required surgery to repair, and sidelined him from training for three weeks.

Despatie, who missed most of 2011 with bursitis and tendinitis in his left knee, was doing an inward three-and-a-half somersault, a dive he'd executed thousands of times before.

He performed the dive again for the first time about two weeks ago in Rome, posting on Twitter:

"Today has been a memorable one! This morning I did ‘THE’ dive again..It went well! I was a bit emotional after..But a big step for me! #proud."

It's not the first time the diver has faced adversity just weeks before an Olympics.

Four months before the Beijing Games in 2008, Despatie fractured his foot in an injury that prevented him from training in the run-up to the Olympics. He went on to win silver in the three-metre individual event.

Canada has two diving medals in London. Emilie Heymans and Jennifer Abel won bronze in the three-metre event, while Roseline Filion and Meaghan Benfeito claimed bronze in the 10-metre synchronized event.

Despatie will compete in the three-metre individual event on Aug. 6.
