West Coast captain Darren Glass says the Eagles can still play a big part in the finals but first they must snap a seven-game losing hoodoo against Collingwood on Saturday night.
The Eagles, who have not beaten the Magpies since round two in 2007 must win to keep alive their fading hopes of an important top-four finish.
Victory would leave them needing to beat Hawthorn at the MCG in their final home-and-away match to guarantee a double chance in September.
They beat Port Adelaide by 48 points at AAMI Stadium yesterday but were far from convincing, particularly when outscored in the third term.
West Coast midfielder Luke Shuey said he expected Collingwood to bounce back from their loss to North Melbourne on Saturday and claimed his team would "get flogged if we put up what we did in that third quarter".
Glass said that with key forward Josh Kennedy - who kicked two goals in his comeback match for East Fremantle yesterday - a likely inclusion against the Magpies and veteran Andrew Embley starting to find form after a long injury lay-off, the Eagles remained in the premiership mix.
"I think we can have a big impact. Regardless of where we finish, I'm pretty confident our best is good enough to take anyone on," he said.
"We're not playing our best footy yet but I think we can going forward.
"We're very excited to take on Collingwood."
Daniel Kerr is likely to face match review panel scrutiny for a behind-the-play incident in the second quarter that left Port teenager Chad Wingard on his haunches in the second term.
In Kerr's favour was that Wingard played out the match.
The Eagles will also monitor a hip injury to Andrew Gaff.
Adam Selwood was substituted off at quarter time with concussion sustained in a collision with teammate Jacob Brennan.
Worsfold said Selwood joined his teammates in a meeting after the game and "cracked a smile".
He faces concussion tests during the week.
"We've had dozens of concussions over my time coaching here," he said.
"We've got a great protocol that we work through, so it will be treated like they all have been.
"We've got all the data and research from our guys and from the AFL.
"Concussion in the AFL is treated extremely seriously. Our doc asked at quarter time and we said we could give Adam another five minutes to see how he comes around and whether we could release him to come back on.
"But we felt, both with the doc and myself, that was unfair on Adam and decided to sub him out then.
"Now it's just normal protocol. Follow that and most times players come up ready to go next week.
"Occasionally, they don't."
