Watch: Andy Murray 'pain free' after hip surgery

Andy Murray says he is "pain free" after hip surgery but that his chances of playing singles at Wimbledon this year are "less than 50%".

Murray had hip resurfacing surgery in January, which he said meant it was possible he would not be able to play professionally again.

But the three-time Grand Slam champion said it was the only option if he wanted to return to competitive action.

"The rehab is slow but going well," the 31-year-old Briton said.
