Hawthorn coach Alastair Clarkson says his side will need to be on its guard against the Demons.

Despite Hawthorn dominating the Demons since 2006, winning 12 in a row, Saturday's clash shapes as a danger game against Paul Roos' improving outfit.
 
"(Ruckman Max) Gawn has given a lot of supply to the midfield group and they've played some pretty good footy," Clarkson said.
 
"We need to be on our guard tomorrow (Saturday) to make sure we win that midfield battle."
 
The Hawks will unveil their fourth debutant for the year with rookie Kade Stewart named to play.
