Mystery stomach bug threatens tennis tournament

The Wimbledon champion Petra Kvitova has become the latest player to pull out of the tennis at Indian Wells in the US because of a stomach bug that is threatening to overshadow the whole tournament.

Former French Open winner Francesca Schiavone, French 14th seed Gael Monfils, ninth seeded Russian Vera Zvonareva, American Vania King and Jurgen Melzer of Austria all withdrew from matches on Sunday while Magdalena Rybarikova, Philipp Kohlschreiber and Andreas Seppi pulled out on Saturday.

Tennis Correspondent Jonathan Overend told BBC Radio 5 live Breakfast more about this mystery stomach bug.
