Kim Clijsters has pulled out of her second singles match in the Fed Cup tie against Estonia because of an injured left foot.
Justine Henin, who broke her left little finger during training on Wednesday, has replaced her for Sunday's match against Kaia Kanepi. If Henin wins the first match, Belgium will hold an insurmountable 3-0 lead.
Even though Henin is right-handed and plays with a single-handed backhand, she had not been slated to play singles this weekend but made herself available because of Clijsters' injury.
Clijsters beat Maret Ani 6-4, 6-2 Saturday despite discomfort in her left foot. The bruising got more painful overnight, forcing her to pull out of the second match.
