Two-time Grand Slam finalist Vera Zvonareva underwent right shoulder surgery this week and will be sidelined for several months.

Zvonareva started out last year ranked seventh in the world, but she never advanced beyond the quarterfinals in 10 tournaments. She's been sidelined since losing to Serena Williams at last year's London Olympic Games.

The 28-year-old former world No. 2 was the 2010 Wimbledon and U.S. Open runner-up and captured a bronze medal at the 2008 Beijing Olympics.
