The 27-year-old striker has only featured in four first-team matches
this season and has not played since August.
Hammers manager Alan Curbishley has also been without Craig Bellamy with an abdominal problem
recently, with reports earlier in the week suggesting the Wales striker may be ruled out for the campaign if he requires
more surgery.
Zamora, however, is cautious about rushing a return to the first team after netting his treble
against Birmingham City's second string.
He said: "It's been a long time. I don't want to go into the first team not fully fit and
that is the main thing."
"I don't want to go out and not do the team justice and not do myself justice really. Making
sure I am fit enough is important."
"I want to take it slowly, I don't want to break down. I want to make sure I am 100 per cent
before I go back and try and fight for my place in the first team."
