West Ham striker Andy Carroll will miss the rest of the 2014-15 Premier League season after undergoing surgery on a knee injury.
The England international pulled up in the closing stages of Wednesday's 0-0 draw with Southampton, though manager Sam Allardyce was originally hopeful it would not prove to be too serious.
But after meeting with a specialist on Friday, it was confirmed the former Liverpool forward will require surgery.
And the recovery period required will mean it is unlikely he will feature for the Irons again this term.
"Andy Carroll will have surgery on his injured knee on Tuesday following assessment by a specialist on Friday afternoon," a statement on the club's official website read.
"The England international injured his left knee during the second half of Wednesday night's 0-0 Barclays Premier League draw at Southampton.
"The recovery phase is expected to keep Carroll out for the remainder of the 2014-15 season."
Carroll has scored five Premier League goals so far this campaign having missed the first three months with a heel injury.
