CALLUM MCGREGOR is irreplaceable for Celtic according to manager Ange Postecoglou, as the Celtic captain anxiously awaits news on the projected timescale of his recovery from the knee injury sustained in the Champions League loss to RB Leipzig on Wednesday night.
McGregor visited a specialist on Friday morning in an attempt to uncover the extent of the damage his knee suffered in Germany, so all Postecoglou has been able to confirm so far is that it will not be a short-term lay-off for his skipper.
Oliver Abildgaard was the man who came on to replace McGregor during the week, but Postecoglou recognises that the loss of his influence both on and off the field and his ability on the pitch will be keenly felt by his team.
