(Reuters) - Briton Francesca Jones said playing in Bogota without acclimatising to the high altitude led to her collapse mid-serve at the Colsanitas Cup, where she was taken off court in a wheelchair.

Jones, 24, was losing 6-2 5-7 5-3 to Argentina's Julia Riera when the Briton suddenly staggered after tossing the ball up to serve before collapsing on the court as tournament officials rushed to her side.
