PORT Adelaide players will be made to sit through their worst performance of the year in order to keep their finals hopes from slipping away.

The Power are still reeling from Sunday's 84-point record thumping at the hands of cross-town rivals Adelaide at Adelaide Oval.

"You can't wipe that, you've got to show it," Power assistant coach Brendon Lade said.

"Some truths have to come out and they will.

"We'll address it and we'll get better."

In better news for the Power, star midfielder Chad Wingard will train this week in a bid to prove his fitness for Sunday's clash with Collingwood at Adelaide Oval.

"He was running by the end of last week, doing a bit of change of direction on Saturday," Lade said.

"Barring any setbacks and getting through the training sessions, he'll play."

However, defender Matthew Broadbent has been ruled out of the Magpies game with his own ankle complaint.

"We probably rushed him a little bit early in the year and probably paying the price, so I think he'll be at least another week," Lade said.

It was the biggest losing margin in the 20-year history of the Showdown, surpassing the 83-point defeat to the Crows in the 2005 semi-final.

The Crows have now taken a 22-21 lead in the overall ledger after winning the past five meetings between the two clubs.

The Power will consider wielding the selection axe for their game with the Magpies.

"I think everyone will be nervous this week," Lade said.

"Losing by that amount in that big a game against the top team (in the competition) shows a few weaknesses.

"Ken's already said in his press conference there is the possibility of changes so I'm sure there will be."

The fifth-placed Power need to win at least one, and maybe two of their last three games against the Magpies, the Western Bulldogs and Gold Coast to secure their place in the finals.

"Our group has bounced back well and we've responded to our losses all year," Lade said.

"We expect no different this week."
