West Ham goalkeeper Jimmy Walker is to have an operation next week on the knee injury he suffered in the play-off final win over Preston in May.
Walker was stretchered off in the play-off final
The 31-year-old fell awkwardly towards the end of the game and was stretchered off with cruciate ligament damage.
"It's a cruciate operation, but it's only one and I'm hopeful that it will go well," he told the club website.
"After that it's just be a case of going through the rehabilitation and waiting for the knee to heal."
Walker replaced Steven Bywater as the regular first-choice keeper towards the end of last season, and he now faces competition from newly signed former Manchester United goalkeeper Roy Carroll when he returns to fitness.
"It's difficult to put a timescale on it, we'll just have to wait and see after the operation," he said.
"I'm hopeful that it won't be too long, though."
