Federer pulls out of upcoming ATP Masters events due to injury


Former world number one Roger Federer has pulled out of the upcoming ATP Masters 1000 events in Toronto and Cincinnati due to a knee injury, tournament organisers said on Thursday.

The 39-year-old, who underwent double-knee surgery last year, reached the quarter-finals at Wimbledon before withdrawing from the Tokyo Olympics due to a “setback to his knee” during the grasscourt season.

This latest injury puts the 20-time Grand Slam champion’s participation in the U.S. Open, which gets underway on Aug. 30, in doubt.
