Adelaide will challenge Richard Douglas’ one-game suspension in a bid to have him available for the AFL grand final rematch.

The Crows will take the case to Tuesday night’s tribunal hearing and they risk a $10,000 fine if they are unsuccessful.

Douglas was charged with rough conduct after his high bump concussed Essendon star Zach Merrett on Friday night at Etihad Stadium.

The incident happened in the first quarter and Merrett was forced out of the match.

It was assessed as careless conduct with medium impact to the head.

Meanwhile, Collingwood key forward Mason Cox has a nervous wait on Monday ahead of Michael Christian’s review of the weekend matches.

The American caught Daniel Howe high with his elbow in the third quarter of Saturday night’s loss to Hawthorn at the MCG and is in trouble.
