West Bromwich Albion boss Tony Pulis confirmed Ben Foster suffered a knee injury in their 1-0 win over Stoke City.
Foster was forced off in the second half, being replaced by Boaz Myhill, and Pulis also has worries over goalscorer Brown Ideye.
He said: "Ben had come off with a knee problem, he felt his knee go from under him and we'll have to get him checked, we need him fit.
"Browny has also taken a knock. He has been good for us. We have only got two strikers Saido (Berahino) and Brown, we have got all these results with just two strikers. They look a good pair."
