ST. LOUIS — Anna Kournikova is out for the season because of a wrist injury.

The Advanta World TeamTennis Pro League said Kournikova made her decision after experiencing pain from tenosynovitis while practicing for what would have been her seventh season with the league.

The St. Louis Aces player has not responded to therapy or a series of cortisone shots.

Kournikova said in a news release that she is "extremely disappointed" that she won't be able to compete this year. She said she planned to work on her rehabilitation and looked forward to next year's season.

She still plans to travel with her team to matches in Philadelphia on Monday, Washington, D.C., on Wednesday, Springfield on July 10 and St. Louis on July 11.
