Venus Williams is done for the season because of a left knee injury that has sidelined her for most of the second half of 2010. In a statement released to The Associated Press on Wednesday, the seven-time Grand Slam champion said she is "very disappointed to announce that I will be unable to play" in the WTA Tour Championships at the end of October and the Fed Cup final between the United States and Italy at San Diego in November. "I have been getting treatment and therapy on my knee and have been making progress but unfortunately must continue to keep weight off my knee for the short term and won't be ready to return to competition in 2010," Williams said. "I am looking forward to returning to full health in time for the start of 2011 season and hopefully having the opportunity to play in both the Fed Cup and WTA Championships next year." She is No. 3 in this week's WTA rankings and went 38-7 with two titles in singles and 18-1 with three titles in doubles this season, earning more than $2.5 million in prize money.
