The on-baller had scans earlier today to reveal the full extent of a knee injury suffered in Saturday’s loss to Collingwood.
The scans revealed a torn lateral meniscus in Prestia’s left knee, which means he is likely to be out for 12 to 16 weeks.
Football Operations General Manager Marcus Ashcroft said Prestia will have surgery this week.
“The results of Dion’s scans have confirmed a torn lateral meniscus in his left knee and as a result he will require surgery,” Ashcroft said.
“There is no doubt we are in the middle of some adverse times, and that is placing extra responsibility on the remainder of the team. However, we have found some positives during this phase and players such as Jarrod Garlett, Henry Schade, Adam Saad, and Touk Miller have all stood up in their first season of senior football.”
