West Brom head coach Steve Clarke admits goalkeeper Ben Foster could face further surgery to cure his groin problem.

Foster has already had one operation, which ruled him out of the last three games against Wigan, Sunderland and Swansea, but the former England international is still troubled by the problem ahead of Wednesday's away clash at Swansea.

Clarke said: "It is possible that Ben could need further surgery. If that is the case, it will be the same timescale as before, that it will be seven to 10 days."
