Murray admits he may need further operation

Britain's former world number one Andy Murray faces a crucial few weeks to find out if he requires another operation in order to return to top-level tennis.

The 32-year-old three-time Grand Slam winner has only just returned to training after being out of action since November due to bruising on his pelvic bone.

He capped a remarkable comeback from a hip-resurfacing operation he underwent in January 2019 by winning the European Open in October.

But Murray may need an operation to remove bone growth associated with the surgery though he could be back in action at the end of March in Miami.

The Scot believes his lack of progress is caused by a common side-effect of his operation.

"I have not had lots of clarity as to what the issue actually is, because it is difficult to tell," he told the British media.

"What I need to do just now is build up in these next couple of weeks to really test it. Hopefully it responds fine. I should know by the end of next month whether I'm good to play or not with it."
