Andy Murray thinks more top players will follow Australian women's world number one Ashleigh Barty in pulling out of next month's US Open because of concerns over the coronavirus pandemic.
The Grand Slam is set to take place behind closed doors from 31 August at Flushing Meadows in New York.
Barty said there are "still significant risks" in going to the United States.
"I think we will see it quite a bit. It's everyone's personal decision," said Murray, who plans to play.
The 33-year-old Scot is hoping to play too in the Western and Southern Open, which immediately precedes the US Open and also takes place at Flushing Meadows in a safety bubble.
