Are the courts dangerous?published at 10:15 British Summer Time 7 July 2017
France's 12th seed Kristina Mladenovic complained about a "damaged" court at Wimbledon, claiming poor surfaces are the talk of the players' locker room.
The 24-year-old twisted an ankle in the warm-up and damaged a knee during her second-round defeat by American Alison Riske on Court 18 yesterday.
Mladenovic said both players wanted to stop after only two games "in case something bad happened".
The All England Club said the courts were as "playable as per normal".
Temperatures have reached 30C at Wimbledon, with around 60 people treated by the St John Ambulance for heat-related symptoms on Thursday.
The Met Office is predicting highs of 26C on Friday and 23C on Saturday, but with more cloud cover on both days.
