LONDON (AP) - Martina Hingis vs. Joe Calzaghe might be a mismatch either on the tennis court or in a boxing ring.
Going head to head on the dance floor might be a close run thing.
A five-time Grand Slam winner currently serving a two-year ban after testing positive for cocaine, the 28-year-old Hingis has signed up to take part in the seventh season of BBC's reality talent show 'Strictly Come Dancing,' which starts Sept. 18.
Calzaghe, a retired former world super-middleweight and light-heavyweight champion, is another of the sports stars in the competition alongside TV presenters and soap actors.
Olympic long jumper Jade Johnson, cricketer Phil Tufnell and jump jockey Richard Dunwoody are also taking part.
