Carroll came on from the bench as a 55th minute substitute but was in discomfort as he took a knock then battled with a problem with his knee that he has already injured this season. Carroll was immobile for the last twenty minutes of the match meaning the Hammers were effectively down to nine men after Adrian’s sending off earlier.
“The sad thing is the injury to Andy Carroll”, Allardyce told reporters at his press conference after the game.
“It was the same knee – took a kick onto it and we hope that staying on hasn’t done any more damage. It could be two weeks that he is out. We’ve got three goal scorers there so I’m not too concerned.”
Carroll was forced to leave the ground on crutches.
