Kim Clijsters will be out of action for the rest of the season but does not need more surgery on her wrist after suffering an injury in the Belgian Open.

Clijsters official website said on Sunday that doctors had reassured her the new injury was not as serious as the last one.

Her surgeon said the old condition had completely healed and she was suffering from a new problem in the same area.

Clijsters quit her semi-final against Russia's Elena Bovina midway through the second set on Saturday when she felt pain on her problematic left wrist.

The former world number one was playing her first tournament for almost five months after suffering torn tendons and having surgery on the wrist to remove a cyst.

Clijsters has been advised to ice the wrist and have anti-inflammatory treatment.
