West Ham have moved quickly to bolster their attack after Andy Carroll's latest injury.

The Hammers have signed former Fulham striker Mladen Petric on a one year deal.

Manager Sam Allardyce has acted after only having Modibo Maiga and Ricardo Vaz Te fit up front.

The club have confirmed that Carroll has suffered a new problem with his foot in training.

It is not clear how long he will be out, but it has been reported it could be as long as four months. 

Carroll has not played since his £15 million move from Liverpool in the summer.
