Andy Murray has revealed that he may be facing a third hip operation to clean up bone growth from his last major surgery session as the rehab of the former No. 1 takes another frustrating detour.

The 32-year-old Scot told London media that his tennis future remains uncertain as he attempted to begin practise this week – even while dreaming of a long-odds wild card entry into the Miami Masters beginning in mid-March.

“It’s been unbelievably complex. At the Davis Cup I was diagnosed with this bone bruise on the pubis, which was mild and obviously not a big deal, but they can sort of niggle on if they are not handled properly,” Murray said of his hip resurfacing procedure done in January 2019.

But he confessed: “It didn’t really get better. I started rehabbing, I started hitting a few balls, I started running again on the treadmill and stuff to try and build back up.

“Because of metal in the hip, it is extremely difficult to get a clear diagnosis on the scan. I then had to have a bone scan.”

The result, the double Wimbledon winner said, was that doctors are unsure if he needs to have some excessive bone growth removed, which would delay any return to the courts.

“My pain was not getting better. I was basically like, ‘Look, I am not happy with this diagnosis,” he said.

“What I need to do just now is build up in these next couple of weeks to really test it. Hopefully it responds fine. But, if it doesn’t, then I need to potentially have that (extra bone growth) removed.”

Murray last played in a Davis Cup match last November after earning a surprise title in October at Antwerp.

His latest medical report came a day after Queen’s Club touted his potential return to the pre-Wimbledon grass event in June, a tournament he has won five times.
