Despite David Noble denouncing the prospect of a raft of changes to his side following last week's loss to Fremantle, there are a number of players under consideration for a call-up to the senior side.

Port Adelaide has been in electric form in recent weeks having won three straight games. A movement of the magnets could be just what's needed to shut off the Power.

North Media looks at who is in the mix.

After missing the trip to Perth due to suspension, key forward Nick Larkey is a near certainty to return to the side to take on the Power.

Larkey is the Kangaroos' leading goalkicker by some distance this season with 17 majors for the year so far. He was, at one point, leading the Coleman Medal race.

North's forward structure struggled without its leading man on the weekend and only managed three goals for the entire clash with the Dockers.

Larkey's return will most likely see Josh Walker shift back to replace the injured Ben McKay in defence. However given the number of tall forward options at Port Adelaide's disposal Matt McGuinness could come into the side for a senior debut.

The late exclusion of Aidan Corr saw McGuinness called up as an emergency for the Carlton clash, however Miller Bergman was favoured to take a place in the Roos' defence over the third-year player.

He racked up eight marks and 14 disposals against a strong Geelong side on the weekend as he continues his run of strong form.

Charlie Lazzaro impressed in a high half-forward role at VFL level and continues to develop his game at reserve level.

Lazzaro has spent time in a variety of positions so far this season, and his capability to play in the middle, on the wing or in the forward line could provide some added unpredictability to Noble's side.

His goalkicking radar wasn't quite dialled in against Geelong as he finished with two behinds, but he also finished the game with 17 disposals, five tackles and four clearances.

Should versatile defender/wing player Luke McDonald fail to prove his fitness before the clash either of McGuinness or Lazzaro could come in to replace him. He failed to train with the main group in Wednesday's main session.

McGuinness would be the more 'like for like' replacement in the backline while Lazzaro could come in if Lachie Young or Flynn Perez are entrusted with a defensive role.

Second-year midfielder Tom Powell has also continued to bang the door down for a senior return with another strong performance on the weekend.

Since Noble said he wanted his young players to find a strong run of form at reserve level before becoming eligible for a senior recall Powell has performed strongly against Frankston, Carlton and Geelong.

He finished the clash with the Cats with 23 disposals.

First-year midfielder Jason Horne-Francis trained away from the main group during Wednesday's main training session. Should he be unable to get up for this weekend's clash Powell could be primed to chop into his midfield spot.

Charlie Comben also played well at reserve level against Geelong, making his return from the knee issue that kept him sidelined against Carlton.

The key forward kicked two goals against the Cats and impressed with his strong marking ability both in the contest and on the lead.

His current knee issue is being managed however, and the inability for him to put together a strong training block may hurt his chances of a senior recall.

Recent injuries to defensive options McKay, Bergman and Aiden Bonar may have opened a place in the backline for one of Kyron Hayden, Josh Goater, or Jackson Archer to step into.

Hayden travelled with the senior team to Perth last week, so a lack of VFL minutes may hinder his match fitness and likelihood of being selected.

Goater was putting some strong form together at VFL level before suffering a concussion against Carlton in the VFL two weeks ago. The Port clash may come too soon for him to make his senior debut.

Archer has shown steady signs of improvement at reserve level so far this year and has impressed with his willingness and application in the contest, however further development is likely required before a maiden call-up comes his way.
