Brisbane coach Michael Voss says seizing momentum will decide their AFL clash with Adelaide on Sunday.

The Lions travelled to Adelaide buoyed by a breakthrough first win of the season last week to climb of the bottom of the ladder.

"A win does change the emotional state of mind, that is for sure, but unfortunately you get an opponent again the next week so you don't get to live with it for that long," Voss said on Saturday.

"Whether you have lost or whether you have won, you have got to get over it pretty quick."

Voss said Sunday's AAMI Stadium encounter with the 12th placed Crows would hinge on which side capitalised when they had momentum - a factor his side was struggling with.

"It's about how do you minimise the damage when they have it (momentum) and how do you maximise your opportunity when you do," he said.

"Because you get a really short window, sometimes it's five minutes and sometimes it's 25 minutes or a quarter - we have got to make sure when we do get that opportunity, and it will come during a match, that we make the most of it.

"And likewise, if Adelaide do come, how do we keep our composure."

Brisbane lost key midfielder Tom Rockliff to a calf injury and dropped defender Matt Maguire, while recalling experienced Ashley McGrath and youngster Tom Collier.

Voss has picked the brain of his new fitness coach Brett Burton, the former high flyer who retired last year after a distinguished playing career with the Crows.

"He has been very, very useful," Voss said.

"He has certainly helped in our preparation, and if you believe in preparation and how much of an impact that can have on you game day, it's pretty important."

The Crows summoned forward Taylor Walker from a two-game spell in the SANFL and also fringe players Jared Petrenko and Myke (Myke) Cook to replace axed Richmond recruit Richard Tambling, Jack Gunston and Chris Schmidt.

Crows assistant coach Mark Bickley said Brisbane's lowly status was irrelevant to the South Australian club.

"They haven't been going too badly, to be honest," Bickley said on Saturday of Brisbane.

"They play a contested style of footy, they had their first win last week, they get some key personnel back in (captain Jonathon) Brown and that makes a big difference.

"We are under no illusions, it's going to be a very tough game.

"They have lost a number of games this year by small margins so perhaps where they sit on the ladder isn't indicative of their form."
