Brownlow Medal markets have been thrown into chaos and Hawthorn left fuming by the one week suspension of Hawks skipper Shane Crawford at the AFL tribunal.

Crawford had pleaded not guilty to rough play against Port Adelaide's Brett Montgomery, with the Hawks very likely to appeal against both verdict and suspension.

In other decisions, Hawthorn's Campbell Brown will also miss the game against the Western Bulldogs after being suspended for a week for striking Montgomery while Hawks ruckman Peter Everitt was found not guilty of striking the same player.

Brisbane had mixed fortunes, with full-forward Alastair Lynch not guilty of striking but defender Darryl White received a one-week ban for kicking.

Adelaide ruckman Rhett Biglands received a hefty four-week suspension.

Crawford said the tribunal verdict would leave players thinking twice about making any body contact.

"I came here pretty confident of getting off but I suppose you can't come in to any tribunal hearing confident," Crawford said.

"We will look at it tomorrow and see what we can do, but it's very disappointing."

Crawford admitted he was watching Montgomery before leaping high in the air as he turned to look for the ball in flight.

The Hawk captain's legs hit the upper body of the Power player before both crashed to ground.
