Despite both being bothered by injuries, Novak Djokovic and Serena Williams will be the top seeded players in the upcoming 2016 U.S. Open Tennis Championships. The event will take place on Aug. 29-Sept. 11 at Flushing Meadows, New York.

Both Serena Williams and Novak Djokovic have lackluster performances in the recently concluded Rio Olympics 2016. Williams is reportedly dealing with a shoulder issue, while Djokovic has a sore wrist. Both players have been taking some time off the courts in order to prepare for the Grand Slam.

According to TSN, Williams barely held on to her position as the top seed of the tournament after Angelique Kerber nearly overtook her in the WTA rankings this week. Kerber will have to make do with a no. 2 seeding behind Williams, followed by Garbine Muguruza and Agnieszka Radwanska, respectively.

Williams is a six-time winner at the U.S. Open, and will be looking to add to her already impressive slew of Grand Slam Titles. Meanwhile, Novak Djokovic will be returning to Flushing Meadows to defend his 2015 U.S. Open title.

Rio Olympics gold medalist Andy Murray is seeded second, followed by Stan Wawrinka. Spanish star Rafael Nadal is seeded fourth. Nadal has also been suffering from a wrist injury which he sustained at the French Open. Instead of continuing to rest his injured wrist, Nadal opted to compete in the Olympics, where he won a gold medal in the men’s doubles event. Nadal also played in the Cincinnati Masters, which Djokovic decided to skip last week.  

Other notable contenders in this year’s event include Milos Raonic, Juan Martin del Potro and Serena’s sister Venus. She was also racked with  health problems and made early exits in her most unsuccessful Olympic bid to date. The main draw will be announced on Friday.
