Connor Blakely and Ed Langdon are both set to undergo surgery - ruling the Fremantle pair out for the rest of 2017.
Blakely was forced from the ground on the weekend with a shoulder injury, while Langdon hasn't played in 2 months due to a knee complaint.
“Connor had quite a significant shoulder injury at the weekend, while Ed’s PCL injury was quite significant, and he’s had some challenges along the way,” Jason Weber told the club website.
“Both Connor and Ed will have surgery in the coming week and will miss the rest of the season.”
They are expected to both return in time for a full 2018 pre-season.
