Justine Henin will miss the rest of the season due to an elbow injury.

The 28-year-old former No. 1 suffered the injury at Wimbledon in July and told her personal website she would not be able to practice again until October.

"I took several medical examinations and it is going in the right direction," she said. "But it is still a slow recovery, so I need to be patient again until the end of 2010."

Henin, a seven-time Grand Slam winner, returned to tennis at the beginning of this season after 18 months in retirement.

She reached the final in her first two tournaments, including the Australian Open, and won titles in Stuttgart and Den Bosch.
