Prague - Defending champion Lucie Safarova pulled out of the WTA Tour's Prague tournament on Wednesday after the world No 28 fell sick.
The 30-year-old Czech fifth seed had been suffering from a heavy cold that got worse after her 3-6, 7-5, 6-3 win on Tuesday over the Slovak Kristina Kucova.
The 2015 French Open finalist Safarova had been scheduled to play compatriot Kristyna Pliskova in the second round.
