Collingwood vice-captain Scott Pendlebury said the Pies expected the Eagles to attempt to stretch their backline after the news forward Quinten Lynch was free to play after his successful tribunal hearing on Tuesday night.

Pendlebury said the Pies would aim to bring the ball to the ground and run it out against West Coast's giant forward line, which regularly features Lynch, Jack Darling, Josh Kennedy and resting ruckmen Dean Cox or Nic Naitanui.
He also said Jolly, who missed the Pies' 49-point loss to the Eagles last month with soreness, would be a "massive in" after they were monstered 59-12 in the hit-outs at Patersons Stadium.
"Getting your No.1 ruckman always helps against probably the best ruck tandem in the league," Pendlebury said.
"We just want 'Jols' to compete and for us guys at ground level. We still got smashed in contested footy and clearances, so we've got a bit of work to do and we're looking forward to getting our hands dirty."
Pendlebury identified the key to winning the game would be owning the midfield, which they failed to do in round 22 as the Eagles won the clearances 47-23.
Swan, who was on return from his two-match club suspension in that meeting with the Eagles, now has three games under his belt.
Pendlebury also believes the Magpies are working hard enough defensively and took a big step in efficiency last week despite their 38-point qualifying final loss to Hawthorn.
"The midfield battle is going to be really important," he said.
"They can be so devastating at the clearances with Cox and Naitanui (and) their ability to hit the ball, so we've got to be on our toes and make sure it's a real battle at the stoppages, a real grind."
With Nick Maxwell (suspended) set to miss Saturday night's clash, Pendlebury says the Pies will need someone to take ownership of the backline given the captain's vocalness on the field.
"In the midfield, I'm still going to do what I can to organise and help, but we need someone in the backline like Heath [Shaw] or 'Reidy' [Ben Reid] or Harry [O'Brien], one of those guys to step up a little bit and fill the gap," he said.
Tyson Goldsack pushed his case for selection on Wednesday by completing training, but Dale Thomas and Dayne Beams were on light duties and left the track early.
Pendlebury said the Pies would use the additional 48 hours rest they've had over the Eagles and "make sure the game is nice and hot as early as possible and put the pressure on them".
He also backed the side to bounce back from last week and earn themselves a preliminary final berth against the Sydney Swans.
"I haven't thought about going out in straight sets because it's not something that I want to do," he said.
"Our boys have played in a lot of finals games and we respond really well in that sort of atmosphere."
