West Coast have picked a teenage debutant "made to play AFL" for Sunday's clash with Sydney at Patersons Stadium.
Perth centre half-forward Fraser McInnes, who turns 19 next Thursday, replaces Quinten Lynch after being in impressive form in the WAFL.
The Eagles are already without Josh Kennedy and Scott Lycett because of injury.
McInnes was a significant inclusion in the main team during a drill at training on Wednesday.
West Coast selected McInnes with pick 28 in last year's national draft and Perth coach Damien McMahon said he had all the hallmarks of an AFL star.
"We've been rapt with him," McMahon said. "His work rate has been excellent, his attitude has been amazing. He's a ripper kid who is made to play AFL.
"It's his first year of WAFL league footy but he's been super consistent.
"He's played the key forward role for us in every game and done a lone hand there for a long period of time. He's great at keeping the ball in his area and barely loses a contest. He either wins the contest or halves it and he's exceptionally good at bringing his teammates into the game."
West Coast coach John Worsfold said McInnes would not be eased into the match as a substitute like fellow first-year players Murray Newman and Ryan Neates have been this season.
Worsfold said McInnes was ideally suited to playing against the highly-efficient Swans, stating he could have been picked earlier if an opportunity had presented.
"He would have been ready in round one," Worsfold said. "He's a big boy, (has) a really strong work ethic, a left-footer, he reads the game well and takes a good mark on the lead and in a contested situation.
"He sees the game pretty well. He's a smart decision maker."
Adam Selwood returns after missing three matches and could be asked to tag dual Brownlow medallist Adam Goodes.
Goodes has averaged almost 23 possessions and three goals from his past three games against the Eagles, and was one of the best players on the ground against Brisbane last week.
"We don't want him running amok, put it that way," Worsfold said."Adam Selwood's played on him before and Mitch Brown has played on him before when he's played forward. I would assume that Will Schofield's probably had some time on him."
Is Dermott Brereton right to say Adam Goodes gets a "good run" with the AFL tribunal?Vote
