Roger Federer's long reign as world men's tennis number one is looking perilous after he crashed out of the Toronto Masters in his first match since Wimbledon.
Federer, who had a first-round bye, lost in 3 sets to unseeded Frenchman Gilles Simon in the second round.
Number two Rafael Nadal continues in the tournament and is getting ever close to Federer's number one ranking.
Federer led the rankings by 1,445 points in January but if Nadal wins in Toronto it would be less than 300.
The Swiss says he has to put the loss behind him and concentrate on upcoming events which include the Olympic Games and the US Open.
