West Ham manager Slaven Bilic has revealed Andy Carroll is "gutted" at his latest injury setback that will keep him out for six weeks.
The luckless Hammers striker suffered a hamstring problem just 12 minutes into Tuesday night's 3-1 win at Bournemouth and, following tests, it is likely he will not play again until the end of February at the earliest.
"It's another one of those, four to six weeks," said Bilic.
"He's a positive lad, but of course he is gutted for several reasons. He felt he was back and enjoying his football. It's not the end of the world, though. If everything goes well he will be back very soon so there is no reason to be negative.
"If it goes as we expect then he will be back for a significant part of the season, the last 10-15 games, with enough time to make a huge impact on our season."
Carroll has been beset by injuries since moving to Upton Park, making just 31 starts in three years following his club-record £18million switch from Liverpool.
He returned to action in September following a long-term ankle injury and then had a spell out before Christmas with a groin strain.
However, Carroll has scored twice in his last four appearances, helping the Hammers to victories over Southampton and Liverpool, so his latest absence is another blow especially as fellow striker Diafra Sakho is still missing with a thigh problem.
