Star Port Adelaide AFL defender Hamish Hartlett is facing a long break on the sidelines after suffering a knee injury at training.

Port general manager of football Chris Davies said the 27-year-old suffered suspected damage to the anterior cruciate ligament in his right knee on Thursday during a routine training drill.

"This is obviously a terrible blow for Hamish and the football club," Davies said in a statement.

"Hamish had started the season well and we saw last weekend what a courageous and skilful player he is.

"It was an innocuous incident that caused the injury. He went to change direction and his leg gave way beneath him.

"We fear Hamish won't be back on the field for some time but, no doubt, he'll continue to contribute as a leader of our football club."

The 27-year-old Hartlett had played all five matches this year for a career tally of 153.

Scans will determine the severity of the injury.

Having dropped their past two matches, the ninth-placed Power take on fifth-ranked North Melbourne on Saturday at Etihad Stadium.
