The Kastles announced today that Serena Williams will not play in Sunday's match against the Kansas City Explorers. Instead, Venus Williams will return to action.
Serena cited that she needs more time to rest her back for the London Olympics.
"After winning Wimbledon and Stanford (the Bank of the West Classic on July 15), I need to rest my back," Serena said in a statement from the Kastles. "Fortunately, my sister and Kastles' teammate Venus has agreed to sub in for me. I'm disappointed that I won't be able to see my D.C. fans and join my team during its historic streak, but can't wait to go for gold in London."
Venus has already played once this season leading Washington to a 20-11 win over the Boston Lobsters. The World Team Tennis Champions are now at 22 straight wins.
You can watch Sunday's match at 7 p.m. on Comcast SportsNet.
