The 23-year-old, who is on loan at Upton Park from Liverpool, returned to the Hammers side for last night's 2-1 win over Queens Park Rangers after recovering from a hamstring strain.
"I will speak to Roy personally and give him the lowdown on his match fitness," Sky Sports News quotes Allardyce as saying.
"He only played twice for Liverpool, he has played 68 minutes for us and now another 18, so he is short of match fitness which I am sure Roy will deal with in the right way.
"[England duty] gives him match fitness if it is done sensibly but I don't want to tell Roy how to do his job. I have to say we have spent a huge amount of time getting him here and because of fatigue he pulled his hamstring in the first game so we have to manage that. If England call him up they will manage that."
Hodgson is expected to name his squad for the remaining 2014 World Cup qualifiers on Thursday.
