Sapp, gold medalists May-Treanor and Greene will be 'Dancing With The Stars'

Olympic beach volleyball gold medalist Misty May-Treanor, retired NFL defensive tackle Warren Sapp and sprinter Maurice Greene make up the athlete contingent of the seventh season of ABC's "Dancing With The Stars."

The roster of contestants was unveiled Monday in New York. The new season premieres Sept. 22 at 8 p.m. ET.

A record 13 dancers will compete on the show. Included are the program's youngest dancer ever -- 18-year-old Cody Linley of the popular Disney Channel
show "Hannah Montana" -- and its oldest, 82-year-old actress Cloris Leachman.

Others contestants include singer Lance Bass, Grammy award-winning R&B star Toni Braxton, Emmy-winning soap actress Susan Lucci of "All My Children", reality-show participant
Kim Kardashian, television actor Ted McGinley, TV chef Rocco DiSpirito, television personality/model Brooke Burke and celebrity comedian Jeffrey Ross.

May-Treanor and teammate Kerri Walsh won their second consecutive gold medal in beach volleyball in Beijing last week, a straight-sets victory that extended their winning streak to 108 matches in a row.

Sapp announced his retirement from the NFL last January. The 13-year player made seven Pro Bowl teams, won The Associated Press Defensive Player of the Year award in 1999, and was a crucial element to the Tampa Bay Buccaneers' Super Bowl-winning defense in the 2002 season.

Greene is a former world-record holder in the 100 meters who won Olympic gold in the event at the 2000 Sydney Games.
