Port Adelaide are optimistic young duo Xavier Duursma and Zak Butters have avoided serious injury following the Power's thrilling two-point win over Richmond on Friday.

Initial fears suspected Duursma may have suffered significant damage to his ACL, with, coach Ken Hinkley hoping scans show a more minor diagnosis.

Butters also suffered a knee injury in the second half of the match and was eventually subbed out of the game after several tests.

Speaking post-game, Hinkley revealed there were some promising signs early for the duo of casualties.

“There was a bit going on out there in the carnage. There‘ll be a couple we need to assess, so I can’t give you updates,” Hinkley said, per Fox Footy.

“Without being too optimistic, we‘re positive (Duursma) might not be the worst case with a knee injury – and we all know what that is, an ACL. It doesn’t mean it’s not, but at this stage, there’s some optimism around that, because they do some tests initially.”

The Power were also hit with setbacks to defender Tom Clurey (cork) and forward pair Connor Rozee (cork) and Orazio Fantasia (ankle).

Thursday's win places the Power in the top-four for the time being, sitting with a 3-1 record after the opening month of action.

Port Adelaide are set to face Carlton next week before clashes against St Kilda, Brisbane and arch-rivals Adelaide.
