Serena and Venus Williams withdraw from U.S. Open due to injuries

Tennis superstars Serena and Venus Williams both announced Wednesday that they are withdrawing from the upcoming U.S. Open due to injuries. Serena said she has a torn hamstring, and Venus said she's suffering from a leg injury. 

Serena, who has won the event six times in her career, was the first to announce she would not participate this year. She said in an Instagram post she was advised to let her body fully recover rather than play in the Grand Slam tournament in Queens, New York, which is scheduled to begin August 30.  "After careful consideration and following the advice of my doctors and medical team, I have decided to withdraw from the US Open to allow my body to heal completely from a torn hamstring," she wrote. "New York is one of the most exciting cities in the world and one of my favorite places to play – I'll miss seeing the fans but will be cheering everyone on from afar."
