The last few weeks for Demons player, Clayton Oliver, has been described as “disastrous” as the player’s recovery of a hamstring injury could rule him out for another month.

Professor of sports medicine at La Trobe University, Dr Peter Brunker, says the hamstring is a “complex muscle.”

“It’s actually three muscles … he initially injured one, and then the second time he injured one of the other ones,” he told Sam McClure and Jimmy Bartel.
