Foster ruled out for six months
West Brom goalkeeper Ben Foster has been ruled out for six months after damaging cruciate knee ligaments.
The 31-year-old England international underwent reconstruction surgery on his anterior cruciate ligaments on Friday after the damage was discovered during an exploratory operation.
Foster, who has won eight caps for England and was a member of Roy Hodgson's World Cup squad in Brazil last summer after reversing his decision to retire from international football, will be sidelined until the autumn.
"Ben is in good spirits despite this obvious disappointment to him - he's already talking about his 'rehab' and wanting to get started on it immediately," Albion's director of performance Dr Mark Gillet told the official club website.
"But he has had a cruciate reconstruction of his left knee following the injury against Stoke and he will be out for six months."
Foster limped out of Albion's 1-0 win at Stoke last weekend and an initial examination suggested cartilage damage and a month's absence from duty.
But it was agreed that if surgeons found more substantial damage during surgery repairs would be carried out at the same time and Foster, who suffered similar damage in his right knee early in his career, awoke to be told of the lengthier absence.
Foster's understudy Boaz Myhill kept goal during West Brom's 3-0 defeat at Manchester City on Saturday and the Wales international is now set for an extended run in the side for the rest of the season.
The only available understudies to Myhill are 20-year-old Jack Rose and teenager Ethan Ross, and Press Association Sport understands the club will assess next week whether to apply for special dispensation to make an emergency signing.
