PORT Adelaide's push for a top-four finish has received a giant boost with the Power regaining young stars Connor Rozee, Xavier Duursma and Zak Butters.

The exciting trio will return for Friday night's clash with Collingwood at Marvel Stadium, which has been moved from the Adelaide Oval due to South Australia's COVID-19 lockdown.

The 2018 draftees are already among Port's most valuable players and last year's minor premiers need them firing ahead of another finals tilt.

Rozee missed last Saturday's win against St Kilda due to knee soreness, but Butters and Duursma have been long-term absentees.

Duursma (ankle) has not played since round four while Butters hobbled off two weeks ago in his first game for three months.

But they will run out against the Magpies as Port look to celebrate star veteran Travis Boak's 300th game in style and consolidate their spot in fourth.

"It's quite remarkable because the three boys have had an impact in our club from the moment they walked in," Power coach Ken Hinkley said.

"They came into the side together, and funnily enough, they come back into the side together at a moment when we need them.

"We certainly think it gives us a boost in our ability, but also in our enthusiasm and our willingness to play the game in an exciting brand."

"I think there's always some risk around particularly Zak and Xavier ... we know how long it can take the absolute cream of the crop to get going when they've had an extended break.

"But the season is coming closer to the end and we need to get them back in our side and playing again at AFL level."

Small forward Boyd Woodcock will also take his place despite being subbed out late against the Saints, but Jarrod Lienert, Martin Frederick and Sam Mayes will all be left out.

Despite Collingwood sitting 11 spots below the Power on the ladder, the Magpies almost pinched a win the last time the teams played.

Port overcame an early four-goal deficit to win by one-point at the MCG in round 10 with Nathan Buckley still coaching the Magpies.

Collingwood will be led by Robert Harvey this time around and have opted to blood Irish recruit Anton Tohill and small forward Jack Ginnivan, bringing the number of Magpies debutants to nine this year.

The Magpies will be without Josh Thomas (concussion) and Callum Brown (dislocated shoulder) against the Power.
