Port Adelaide vice-captain Zak Butters has been cleared of serious injury after being subbed out at half time of Thursday night’s Qualifying Final.

Butters underwent scans which showed bruising to the ribs but ruled out any fracture or injury to the internal organs.

The midfielder will be assessed throughout the week ahead of next weekend’s semi-final against Hawthorn.
