West Ham United forward Andy Carroll is expected to miss the remainder of the season after suffering an injury to the medial collateral ligament in his left knee, the team announced Friday.
The squad said that Carroll will have surgery on Tuesday.
Carroll was injured during Wednesday's 0-0 draw against Southampton, but he stayed in the game because West Ham had used all of their substitutions.
West Ham United manager Sam Allardyce said the club was hopeful that Carroll would only miss four to six weeks.
Carroll, who has five goals and three assists in 14 appearances this season, missed the first three months of the 2014-15 season after an ankle injury.
West Ham is in eighth place in the Premier League and will take on West Brom on Saturday.
