Stoke winger Peter Odemwingie needs knee surgery and faces a long spell on the sidelines.
The Nigeria international, 33, picked up the problem in Saturday's 1-0 win at Manchester City.
He will have the operation in the next fortnight.
"It's a significant injury and unfortunately it's a long-term one but Peter has a great attitude to work and life in general," Stoke manager Mark Hughes told the club's website.
"He's always got a smile on his face and he's going to need those qualities. It will be a long road back but we wish him well.
"He's going to have to wait a couple of weeks before it's actually done but once the operation is done we know he will work extremely hard to get back."
Odemwingie has been left out of Stoke's 25-man Premier League squad, meaning he will not be able to play for the Potters until January at the earliest.
