ADELAIDE hasn't used a tagger all year, but coach Don Pyke won't rule out deploying a negating midfielder to contain the potent Sydney Swans engine room.

The Crows are wary of the damage the Swans midfield can do in Saturday night's semi-final showdown at the SCG.

Dan Hannebery ran riot with 38 touches when the two teams met in round four, while Luke Parker, Josh Kennedy, Kieren Jack and Tom Mitchell are all prolific ball winners.

Pyke told reporters on Wednesday all contingency plans would be on the table.

"That's something we'll consider through the latter part of the week and talk to the players about as a possible go to," Pyke said.

"We had some plans in place last week in the event (Daniel) Wells or (Brent) Harvey started to really generate some ball.

"They've got some really dangerous midfielders, whether it's Hannebery or Mitchell, Kennedy, Parker, Jack, there's a few there.

"We haven't used it, but it doesn't mean it's not there."

Pyke was confident the Crows had a few players who could perform a tagging role if required.

Key forward Josh Jenkins trained on Wednesday after missing Tuesday's training session with the flu.

The Crows changed the dimensions of AAMI Stadium to resemble the smaller surroundings of what they will face at the SCG.

"We set the ground up similar in terms of size so they get a feel for it," Pyke said.

"It's more the dimensions of the ground and what the ground allows you to do from the centre forward.

"The corridor becomes an area, given such a short ground, if you can get control of that area, it allows you to attack goal pretty directly."

Pyke said the Crows had learnt not to get carried away after last weekend's victory.

Last year, the Crows beat the Western Bulldogs by seven points in the first week of the finals before being thumped by Hawthorn.

"The feeling I got talking to some of the coaches and players, there was this euphoric state about a great win and that probably didn't help them get ready for the second week of the finals," Pyke said.

"This year, we've been far more measured in terms we've moved on pretty quickly, we did our review and we focused clearly on Sydney.

"I'd be really disappointed if we weren't able to match their intensity and effort based off them coming off a loss and us coming off a win."
