Roger Federer withdrew from the Western & Southern Open due to a knee injury one day after Naomi Osaka said she wouldn’t play in the event.
The final tune-up for the U.S. Open wraps eight days prior in Cincinnati and is a popular stop, and Federer and Osaka remain entered in the Grand Slam the following week at Flushing Meadows.
Federer, 39, is a seven-time champion of the WSO but event organizers said Thursday they received official word he would not play when the event is held Aug. 14-22.
