Hawks boosted by the addition of key players for decider.
Hawthorn stars Jarryd Roughead and and Grant Birchall are free to play in the AFL Grand Final.
The AFL match review panel handed Roughead a reprimand for his behind-the-play hit on Cameron Guthrie while Birchall was cleared for his bump on Mathew Stokes.
The Coleman Medalist was charged with rough conduct by the MRP but escaped with a reprimand and 93.75 carry-over points.
Roughead appeared to block Guthrie as he chased his opponent but collected the Cats youngster.
In the other incident, Birchall hit Mathew Stokes with a bump during the third term, flooring the Cats midfielder.
Immediately after, Guthrie kicked a goal to put his side 17 points up and Geelong players made a point of remonstrating with Birchall.
However, the Hawks half-back collected Stokes across the chest and crucially did not appear to make high contact.
The Hawks earned their place in the AFL grand final after beating the Geelong Cats, and ending the Kennett Curse in the process, as they ended their 11-game losing streak against their arch-rivals.
Hawthorn faces Fremantle in the final game of the season and the Dockers also looked impressive as they downed the Sydney Swans in a commanding performance in the West.
