Western Bulldogs defender Zaine Cordy has been referred directly to the AFL tribunal over his bump on GWS player Tanner Bruhn.

Western Bulldogs defender Zaine Cordy will front the AFL tribunal over the bump that left GWS youngster Tanner Bruhn concussed.

Cordy made shoulder-to-shoulder contact with Bruhn within five metres of the ball during the final quarter of the Bulldogs' narrow win at Marvel Stadium on Saturday.

But Bruhn's head whipped into Cordy's shoulder because of the force of the collision.

His head also hit the ground when he fell and it is not known which part of the collision caused the concussion.

Bruhn's teammates rushed in to remonstrate with Cordy as the Giants' off-contract forward-midfielder staggered to the bench.

He was assessed and placed in concussion protocols.

The incident was left ungraded on Sunday by the league's match review officer, who referred it directly to the tribunal.

Cordy is not able to accept an early plea and is unlikely to be available for the Bulldogs' must-win clash with Hawthorn in round 23.

The Bulldogs need to win and see Carlton lose by enough to overturn a narrow deficit in percentage to qualify for the finals.

Cordy's teammate Bailey Dale is free to play the Hawks after being fined $3000 for striking the Giants' Daniel Lloyd.

Melbourne forward Kysaiah Pickett was fined $5000 for rough conduct over his tackle on Carlton's Liam Stocker and can play against Brisbane in Friday night's blockbuster.

In other assessed incidents, Adelaide's Tom Doedee was fined $3000 for forceful front-on contact against Cameron Zurhaar and Gold Coast's Sean Lemmens received the same penalty for rough conduct against Geelong's Jeremy Cameron.

West Coast forward Liam Ryan was fined $3000 for striking Fremantle's Brandon Walker in a fiery western derby.

A dozen players were fined a total of $19,000 for engaging in melees during the Dockers' win.

Five players were fined a total of $7500 for engaging in melees during the Melbourne-Carlton clash.
