Everton defender Jarrad Branthwaite is set to have surgery on Tuesday after suffering complications in his recovery from a hamstring injury.
The England international has not featured this season with a troubled hamstring and, though it was hoped he would be back by now, he is set to spend another significant chunk of time on the sidelines.
Branthwaite's recovery suffered a setback this week and after discussion with the specialists at Everton it was decided to operate.
The club says he will then spend time on a rehabilitation programme under the supervision of Everton's medical staff.
