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.

โ€œThere was a bit going on out there in the carnage. Thereโ€˜ll be a couple we need to assess, so I canโ€™t give you updates,โ€ Hinkley said, perย Fox Footy.

โ€œWithout being too optimistic, weโ€˜re positive (Duursma) might not be the worst case with a knee injury โ€“ and we all know what that is, an ACL. It doesnโ€™t mean itโ€™s not, but at this stage, thereโ€™s some optimism around that, because they do some tests initially.โ€

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.
