Australian Open runner-up Jennifer Brady has withdrawn from the US Open because of an injury.
Brady, a semifinalist last year in Flushing Meadows, has not played competitively since being forced to retire from her second-round match against Jelena Ostapenko in Cincinnati. The U.S. Tennis Association did not specify her injury.
Ostapenko, the 2017 French Open champion, also pulled out Monday for medical reasons.
Johanna Konta also pulled out of the tournament hours before she was set to play her first round match against France's Kristina Mladenovic. The reason for her withdrawal is not clear.
On the men's side, Jo-Wilfried Tsonga also withdrew. The 2008 Australian Open finalist has a right leg injury.
