Injured Port Adelaide duo Xavier Duursma and Zak Butters are both set for lengthy stints on the sidelines in the fallout from Friday night's win over Richmond.
It is, however, somewhat of a positive outcome for Duursma, with initial fears he hay have ruptured his ACL.
Duursma suffered a significant hyperextension of his right knee and will now undergo surgery on the lateral ligament in the coming days.
His return date will become clearer over the next few weeks.
Meanwhile, Butters will seek further medical advice around the ankle syndesmosis injury which caused him to be subbed out of the game.
