Wolves were understood to have rejected a third bid from the Hammers for the 26-year-old on Thursday morning.
When asked about the transfer situation, Allardyce told reporters: "It is stuck - that's the answer.
"I don't know how that will pan out now. I think that we'll just have to wait and see.
"For me, it is on the backburner because Saturday is the most important thing for me and then if it is to be done after Saturday we'll see where we are."
West Ham mark their return to the Premier League at home to Aston Villa on Saturday.
