Injury-plagued defender Steven May has gone under the knife after a minor injury setback over the Christmas break.
The 28-year-old experienced discomfort in his knee over the festive period, with the procedure expected to keep him away from the main group at training.
Meanwhile, Joel Smith also had surgery after standing on a sharp object at the beach.
Performance manager Darren Burgess didn’t expect the injuries to hamper the pair’s 2020 season.
“They’ve both had minor setbacks through no fault of their own,” Burgess told the Melbourne website.
“Maysie had a cyst pressing on the nerve of his knee which required some treatment.
“His pre-season has been outstanding so far and this won’t affect his program going forward.
“Joel cut his foot while on holidays which was pretty unlucky.
“He treated it straight away and did all the right things, but that wound got a bit infected, so he’s just had to look after it.”
