Brisbane's 27-point victory over a flat Port Adelaide at AAMI Stadium on Saturday showed with painful clarity that the Power will be the deepest of trouble if they cannot keep Dean Brogan on the park.

Port entered the game without a senior ruckman after Brogan withdrew with a shoulder complaint and were well beaten 16.12 (108) to 11.15 (81).

The in-form Lions galloped 49 points clear before halftime.

Captain Jonathan Brown kept up his string of prime displays by nailing five first-half goals while his offsider Brendan Fevola kicked three - two of them brilliant - and teed up several others.

Justin Sherman (four goals) also capitalised in attack, while tall the duo of Matthew Leuenberger (26 hit-outs) and Mitch Clark (21) took full advantage of limited opposition at the stoppages.

Power coach Mark Williams revealed that off-season efforts to recruit another senior follower were thwarted by a lack of money.

He also said Melbourne's Mark Jamar had indicated a willingness to move to Port before changing his mind.

"I know for certain that we didn't have the finances to get any significant ruckman," Williams said.

"We tried to get Jamar and he's pretty significant, indicated he was coming and then changed his mind, so we went out of our way to try to bolster that but just because you want them doesn't mean they're going to come.

"Finances do limit if you want to make a big play on a big name it is pretty hard."

Michael Rischitelli and Brent Staker were other strong contributors for Brisbane, who were set back by a reports for Clark and Ashley McGrath and an apparent calf injury for the decorated midfielder Simon Black, though coach Michael Voss said the Brownlow Medal winner would be in contention for next week.

"This is big for us, this is a really big effort," he said.

"To get that far in front into the third quarter and come away from AAMI Stadium and have a win away from home breeds an enormous amount of confidence, not only in the form of the players but the faith in our structures and what we're trying to achieve."

Port's efforts were uneven, with Kane Cornes, Steven Salopek and Danyle Pearce among their best.

While Port battled to contain Brown, the less heralded Brent Staker played a key role, winning plenty of the ball and stretching Port's defence to create space for others.

Brown's second and third goals arrived around a minute either side of the first change and he, Sherman and Fevola added more as the margin slipped out as far as 49 points before Port notched a pair of long overdue majors to peg it back to 39.

Fevola's second was a party trick from deep in the forward pocket and at the main break his tandem with Brown had played a key role in dismantling Port's defence.
