West Ham United striker Andy Carroll is set to be out for six to eight weeks after suffering knee

Carroll is currently on loan from Liverpool, and has already missed a month of the season with a hamstring injury.

The news will be a bigger blow as the striker scored his first goal for the club last weekend against Spurs.

Allardyce told BBC Sport: "It's pretty severe. We didn't expect it to be quite as severe.

"It's going to be about six to eight weeks. It's a blow for us and Andy."

Having already missed a month due to a hamstring injury suffered against Fulham in September, Carroll had netted only once in 10 games for the Hammers.
