West Bromwich Albion defender Jonas Olsson is facing Achilles surgery.
Dutch orthopedic surgeon Professor Niek Van Dijk will carry out the operation in Portugal on Friday with the Baggies estimating Olsson will be out for four to six weeks.
"I have been struggling with this on and off for some time and I've come to the point where it feels like surgery would help it," the Sweden international told the club's official website.
"The recovery time is short so I hope to be back 100 per cent some time after the New Year."
