PHOENIX, Arizona, July 18. A knee injury suffered three weeks ago isn't keeping Cameron van der Burgh out of the world championships, as the South African announced that he's set to compete in Barcelona at the end of the month.

Van der Burgh tweeted on Tuesday that he was departing South Africa for final preparations for the world championships, and the chance to win a couple of world titles in the sprint breaststroke events. Van der Burgh is the reigning Olympic champion in the 100 breaststroke, a win that stirred controversy when he admitted to taking extra illegal dolphin kicks in the 100 breast final as a way to stay on the same playing field as others who were performing the same action.

Van der Burgh's intention to swim in Barcelona is likely spurred on by a desire to pay tribute to his fallen friend Alexander Dale Oen, who won the 100 breast in 2011. When van der Burgh won in London, he pointed skyward after his win in acknowledgement of Dale Oen.

Van der Burgh won bronze in the 100 breast at the 2011 world championships, behind Dale Oen and silver medalist Fabio Scozzoli. Scozzoli is also swimming at worlds this year, ranked second in the world. Van der Burgh is also the world record holder and 2009 world champion in the 50 breaststroke.

The South African team is holding a brief training camp in Rijeka, Croatia, before boarding a plane to Barcelona.
