Wimbledon finalist Justine Henin-Hardenne has pulled out of the Belgium team to face the United States in the Fed Cup semi-finals this weekend.
"She will not play because she is not 100 percent fit," a team spokeswoman on Wednesday.
Henin-Hardenne lost the Wimbledon final to France's Amelie Mauresmo on Saturday, four weeks after she had retained her French Open crown.
Her place in the Belgian team will be taken by Leslie Butkiewicz, the spokeswoman said.
