LOS ANGELES (AP) - Two-time Olympic beach volleyball gold medalist Misty May-Treanor had surgery to repair a torn Achilles' tendon on Tuesday, a day after she said on "Dancing with the Stars" that she was dropping out of the competition.

May-Treanor appeared at the conclusion of Monday's show on crutches and with a cast on her left leg to announce that she injured herself while rehearsing on Friday and would withdraw from the popular ABC dancing competition. "I was like, 'OK, I'm an athlete. Tape it up and get back out there,"' she said in a release issued by USA Volleyball. "I never thought in a million years, especially in ballroom, that I would hurt myself."

May-Treanor and her professional dance partner, Maksim Chmerkovskiy, scored 21 out of 30 for their previous foxtrot, mambo and paso double routines.

The Olympic champion in Athens and Beijing with partner Kerri Walsh, May-Treanor had planned to take time off from beach volleyball to have children with her husband, Florida Marlins catcher Matt Treanor.

"I'm extremely disappointed for Misty," Walsh said from Dubai, where she is competing in an international beach volleyball tournament. "She is disappointed that she could not continue, as she was really enjoying the experience."
