Coach John Worsfold says West Coast's tall forwards won't be distracted if Collingwood defender Chris Tarrant brings the rough tactics which he used against Lance Franklin into Saturday night's semifinal at the MCG.
Tarrant attacked Franklin before the opening bounce and the pair scuffled repeatedly during last Friday night's qualifying final.
With Magpies captain Nick Maxwell suspended and Eagles forward Quinten Lynch cleared by the tribunal, West Coast will take a significant height advantage into the match, which will test Collingwood's defensive depth.
Worsfold said his players were only interested in playing football.
"Concentrate on the contest. That's the key thing," he said.
"If a tactic off the ball or away from the contest puts you off competing then it's had its impact.
"So, when the ball is in your area you play footy."
The Eagles didn't select Lynch for their last night game at the MCG, but recalled him for last Sunday's elimination final to play alongside Josh Kennedy and Jack Darling.
Darling and Kennedy both kicked four goals against the Roos, Lynch booted three and Dean Cox and Nic Naitanui snared one each as the Eagles won by 96 points.
Worsfold said the coaches wanted to see how Kennedy and Darling played as a two-pronged attack before the finals, but liked having the extra big man last week.
"We've got complete faith in that structure," Worsfold said.
West Coast must replace Beau Waters after his season ended because of a foot injury.
Worsfold said he would consider bringing Mitch Brown in as a key defender, releasing Will Schofield for a running role. Lewis Stevenson and Ash Smith were in the mix. Matt Rosa had to pass a fitness test on his collarbone yesterday and will almost certainly play if fit.
