West Ham boss David Moyes has confirmed that forward Michail Antonio is out for the remainder of the campaign.
"He's going to have an operation on his hamstring and the biggest thing now is to get him ready for next season," said Moyes.
"We'll miss his great strength and pace.
"He picked up a hamstring injury at the end of last season and has never really recovered from it. He's had some big injuries since I've been here."
