Port Adelaide forward Sam Powell-Pepper is out for the rest of the 2024 season after rupturing his ACL.

Scans confirmed the cruel blow on Saturday after Powell-Pepper was withdrawn from Friday night's win over St Kilda mid-game.

The Power have confirmed Powell-Pepper will undergo surgery.

“We are incredibly disappointed for Sam," Port Adelaide Head of Medical Services Tim O'Leary said in a club statement.

“Sam is a dedicated and diligent athlete who attacks his training with unrelenting intensity, and will no doubt approach his rehab the same way. He will continue to be as involved as he can, as a leader and important member of our playing group.

“It's such a tough injury for a footballer to go through. We're all behind him and we know he'll come out the other side stronger and more determined.”

Scans also indicate a low-grade hamstring injury for captain Connor Rozee.

More to come.
