CHAD CORNES might be starting to regret his stellarbest-on-ground performance against Brownlow Medallist James Hird two weeks ago.

Cornes' days of running freely through the lines gatheringpossessions at will appear numbered, as the versatile Power star prepares foranother big challenge.

This week Mark Williams has designated the elder Cornes the confrontingtask of minding Lions' power forward Jonathon Brown.

"Chad'sbeen playing really well doing different roles and he's played well on Brownbefore," Williams said prior to boarding the team's flight to Brisbane on Friday.

"Chadreally does lap up the challenge and I think he and Brown have beenhead-to-head a few times and they're not far apart in wins and losses. Eachtime I think they look forward to it."

At 192cm and 96kg, Cornes gives away six kilograms to Brownbut possesses the athleticism to run with the dangerous Lions match winner.

"He's [Brown] a wonderful player and a wonderful leaderso he'll be one of the major focuses," Williams said.

"It depends on whether Browny is playing full forwardor not. If he pushes up the ground he's probably more Chad; if he'snot, he's probably more [Darryl] Wakelin."

The Power will be buoyed by the form they displayed in theirlast start, with an emphatic win over in-form Essendon.

The Lions, on the other hand, slumped to their third loss infour weeks, however Williams said the Lions' recent poor form was irrelevant.

"Having had the break it gives both sides a chance totake a breath and re-group. What the form was prior to the break really doesn'tmatter – everyone has to re-establish their form now."

The Power have declared their intent to play finals footythis year and will need to win at least five more games to achieve that goal.

With three of Port Adelaide's next four games scheduledinterstate, Williams emphasised the importance of notching up as many awayvictories as possible.

"You have to win quite a few away games [to qualify forfinals]. We've already won three, but we've also lost some home games.

"You always have to try to keep your head above waterso this will be an important game if we can win," Williams said.

"But that blue sky that Brisbane has, you're never quite sure whatyou're going to get up there, so it's always a good challenge."

Meanwhile, All-Australian Shaun Burgoyne is expectedto line-up for the team on Saturday despite failing to train on Wednesday.

Young defender Alipate Carlile travelled with the team to Brisbane and will remain on standby shouldthe dynamic midfielder not come up in time.
