Port Adelaide is in line to receive a much-needed boost to its forward line ahead of its do-or-die semi-final clash with GWS this Saturday night.

Bulldozing key forward Charlie Dixon, who hasn't played for the Power since Round 20 due to a nagging foot injury, could return to Ken Hinkley's side this weekend, according to the club's official injury update on Monday evening.

Dixon is understood to be running without discomfort and will re-enter the Power fray at training this week in an attempt to put his hand up at selection for Saturday.

Fellow key-position goalkicker Todd Marshall is expected to be available for selection despite managing hip soreness.

Meanwhile, defenders Trent McKenzie (ankle) and Dylan Williams (hamstring), who each suffered ailments during Port Adelaide's heavy loss to Brisbane at the Gabba last Saturday, could retain their spots for this weekend's meeting with the Giants.

McKenzie will continue to be assessed throughout the week by Port's medical team after spraining his ankle in the third quarter of last weekend's loss, while scans cleared Williams of significant damage, with the young defender still needing to prove his fitness.

McKenzie, along with Marshall and ruckman Scott Lycett, represented the Power's three inclusions to last week's side, with Francis Evans (omitted), Sam Hayes (omitted), and Tom Jonas (injured) all going out of the team ahead of the bout with the Lions.

Port Adelaide will name its selected semi-final lineup on Thursday evening ahead of the Saturday night fixture at Adelaide Oval.

A loss would see the Power eliminated in straight sets, while a win would see the Alberton club progress to a preliminary final meeting with Collingwood at the MCG next weekend.
