Vera Zvonareva: Has been struggling with illness for some time
Former US Open finalist Vera Zvonareva has withdrawn from next week's tournament because of a virus.
The Russian is down to 16th in the world rankings after a frustrating year that is going from bad to worse.
Zvonareva, who lost to Kim Clijsters in the 2010 final at Flushing Meadows, missed the French Open with a shoulder injury.
She then retired midway through her third-round match with Clijsters at Wimbledon because of the virus, before losing 6-0 6-1 to Serena Williams at the Olympics.
Ranked as high as number two at the end of a stellar 2010, Zvonareva had skipped recent events in Montreal and Cincinnati in a bid to be fit for the final Grand Slam of the season.
