Venus Williams is "very unlikely" to play the French Open, a source in the Williams camp told TENNIS.com. On Monday, the seven-time Grand Slam champion pulled out of next week’s warm-up tournament in Brussels. Williams hasn’t been played since retiring in the third round at the Australian Open in January with a hip injury. She hadn't played before that since the 2010 U.S. Open due to a  knee injury. The French Open begins May 22.—Matthew Cronin
