"We are still speaking with him and we would like to do something, but we have got to be able to fit him in with what we've got and for him to make a contribution to what we are doing here," said Boothroyd.
"We want him to be involved and not here as some sort of mascot, and we will probably decide what we are doing in the next few days."
Boothroyd also confirmed the U's have accepted an offer from Bristol Rovers for defender Pat Baldwin, who has recently been on loan at the Memorial Stadium.
"It is now a case of Pat and his people talking to Bristol Rovers and sorting it out. It will be resolved one way or the other soon," he added.
