Melbourne recruit Michael Hibberd has been ruled out of Round 1 against St Kilda, according the the Demons website.
The club announced that the defender is suffering an Achilles injury and won't be risked next week.
“Michael will not be playing for Casey this weekend. While his Achilles injury is improving, we have decided to take a more cautious approach and he will therefore not be playing in round one,” said General manager of football operations Josh Mahoney.
“We think this is the best way to approach this type of injury, when we consider the entire season and not just round one.
“We didn’t think it was appropriate to push him for round one, when it’s about having him for the whole season.”
