The Wales international played in a friendly at the start of the
month, but the club have now revealed that he needs to go under the knife again on his abdominal injury.
Bellamy originally had surgery in October and although the latest operation is only likely
to sideline him for six weeks, it is a blow as the Hammers had hoped he would now be back in contention for the first-team.
West Ham confirmed the news after Bellamy felt he was not 'quite right' after his come-back
earlier in the month.
Hammers physio George Cooper remained buoyant about Bellamy's recovery.
"He has been absolutely brilliant," said Cooper. "Everything he has done has got him back
to almost being ready and there is a feeling that if he carries on with slight symptoms they are likely to get worse rather
than better. The symptoms have to go."
"The operation will complement he has done before and that should be the last bit he needs
before continuing his strengthening."
There was better news for the Hammers with Bobby Zamora back in full training along with Julien
Faubert and Nolberto Solano.
"He is strong as an ox now," Cooper said of Zamora. "His legs are really good and he is in
good nick. Bobby is always in early, has been working very hard and been very patient."
"It looks to have paid off. His running fitness is as good as anybody's at the club, if not
better."
