West Brom goalkeeper Ben Foster faces a six-month spell on the sidelines following surgery on an anterior cruciate ligament injury.
The England international had initially been expected to miss only a month after picking up the injury in their win over Stoke earlier in March, with the Baggies suggesting the issue was a knee cartilage problem.
However, Foster underwent surgery on Friday and an exploratory operation uncovered a more serious problem, damage to his cruciate ligaments.
