Miller, Zurawski, Gravesen available at Celtic
BBC Sport says the senior trio have all been made available.
Miller, 27, has struggled to find the net consistently since joining the SPL champions from Wolves last July.
But Celtic have strongly denied that he, striker Zurawski, or midfielder Gravesen are being forced out.
A club statement said: "Contrary to ill-informed reports from some media outlets, Celtic Football Club has not placed anyone on the transfer list."
