The Czech Republic will be without Radek Stepanek for next month's Davis Cup quarterfinal against Chile. Stepanek has been ruled out of the Chile match because of a left knee injury. He is not playing at Wimbledon. No. 90 Jan Hajek will join No. 13 Tomas Berdych in the singles at the July 9-11 Davis Cup tie in Coquimbo on clay. Stepanek, ranked 25th, helped the Czechs reach last year's final, where they lost 5-0 to Spain. http://sports.espn.go.com/sports/tennis/news/story?id=5325196
