BRUSSELS — Justine Henin has broken her left little finger during training and is out of the singles for Belgium's Fed Cup matches against Estonia.

The right-hander plays with a single-handed backhand, but the pain was still enough to rule her out for Saturday's opening singles. If she plays at all, Henin might come back for Sunday's doubles.

Henin said the injury would not have kept her from playing in a regular tour event, but because Belgium has such a strong team, there was no need to force her into the singles matches.

The break occurred on Wednesday but the extent of the injury only became clear on Friday.
