Britain's Jones collapses on court in Colombia

Britain's Fran Jones was helped off court in a wheelchair after collapsing during a match in Colombia.

Jones was attempting to serve in the ninth game of a deciding third set in Bogota when she fell to the floor.

The 24-year-old initially lay on her back before rolling on to her side as she was attended to by medical staff.

Opponent Julia Riera walked over to check on Jones and helped lift her on to a wheelchair.

Jones, the British number five, was unable to finish the first-round match in the Colsanitas Cup, a WTA 250 tournament.

"Due to a physical issue, Francesca Jones has withdrawn from her match against Julia Riera at 6-2 5-7 5-3 in favour of the Argentinian," read a Colsanitas Cup statement.

"We wish the British tennis player a speedy recovery."

Jones beat Riera in straight sets last week on her way to winning the W75 Vacaria in Brazil, the eighth ITF title of her career.

Meanwhile, Heather Watson is out of the Charleston Open after a straight-set defeat by Iryna Shymanovich in the first round.

The British number seven was beaten 7-6 (10-8) 6-4 by the Belarusian world number 215.
