Port Adelaide ruckman Matthew Lobbe will miss the next 12 weeks with a torn PCL.
Lobbe suffered the injury playing in the SANFL on the weekend, after he was dropped from the senior side after Round 5.
The 26-year-old will avoid surgery, but will still miss around three months.
“Really disappointing news for ‘Lobes,’ the scans show a full rupture of the PCL, which will keep out for around 12 weeks,” Port Adelaide head of high performance Darren Burgess told the club’s website.
“The timeframes for recovery are pretty similar whether he has surgery or not.
“It’s a fairly standard rehab program that he’ll do, he’ll be in a knee brace for about six weeks, and will commence running in 6-7 weeks.”
