Everton defender John Stones could be sidelined for almost four months as he needs surgery on an ankle injury.

The 20-year-old pulled out of the England squad this week after he was carried off on a stretcher during the defeat to Manchester United at Old Trafford on Sunday.

Specialist medical advice has identified the youngster requires an operation to fix the problem and that will rule out Stones until the new year.

"Roberto Martinez has revealed that John Stones' injury requires surgery and expects the defender to be out for 10-14 weeks," said a statement on


The Everton manager insists despite the lengthy lay-off he is relieved Stones' injury has no further complications.

"John will need surgery, which will give us a perfect recovery for his left ankle," he told

"We expect him to be out for probably the next 10 to 14 weeks depending on how everything goes.

"It's a clear injury - not a complicated injury. Obviously, it's a little bit of a setback because you don't want to lose any players, but in John's case we were very worried in the moment that it happened because those injuries can become a little bit difficult to treat.

"But this one is going to be straightforward and we are already counting down the days for him to come back and we'll make sure he comes back stronger and ready for the final and most important part of the season."
