The situation adds to the midfielder’s tumultuous off-season which included intense trade speculation with Oliver at odds with the club’s standards.
Oliver underwent a minor knee procedure post-season but hit the training track earlier than required for Melbourne’s pre-season campaign.
He did not train on Saturday but made his way to the first day of the training camp before returning home to Melbourne.
Melbourne football manager Alan Richardson said the decision for Oliver to leave early was made on Monday.
“Clayton is taking a break as he continues to deal with some issues. We are continuing to support Clayton and managing his program in a way that prioritises his health and wellbeing,” Richardson told the Age.
“His teammates and staff remain confident he is making good progress.”
MORE TO COME.
