Swimming officials are considering the introduction of underwater video for judging following the controversy over an alleged illegal dolphin kick by South Africa's Cameron van der Burgh in his 100-meter breaststroke victory last week.

Van der Burgh has acknowledged that he took an additional underwater kick at the start of his world-record swim, justifying it by explaining that most competitors do it.

As the fastest qualifier for the Olympic final, Van der Burgh swam in lane four, which is lined with numerous television and still cameras, which clearly documented the infraction. But judges cannot look at the images.
