Roger Federer to miss National Bank Open Toronto and Western & Southern Open with knee injury

Roger Federer will miss the National Bank Open in Toronto and the Western & Southern Open in Cincinnati due to a knee injury.

A bad stretch of the year just got worse for Roger Federer who announced following his Wimbledon exit that he is dealing with a setback in his knee. It's a tricky knee injury he has managed in the last two years after undergoing two surgeries on it.

Federer missed the Olympic Games because of it and now only days ahead of the National Bank Open in Toronto it was announced the Swiss ace will miss those two events as well. The announcement came directly from the ATP Tour and it did not feature a released statement by Federer.

Federer was last seen vacationing with his family in Croatia suggesting that his injury was not serious as many people initially feared. However, this recent development is a very bad sign with the US Open coming in less than a month. Knees heal notoriously slow and there is doubt whether Federer will be ready.

Fans will be hoping that it is only precautionary in order to arrive at Flushing Meadows in peak health however until Federer offers some insight into the situation things are unknonw.
