INJURY-TROUBLED Port Adelaide spearhead Charlie Dixon is raising hopes of making a comeback in Saturday night's semi-final against Greater Western Sydney.

Dixon trained on Tuesday, albeit on restricted duties, as he pushes his case to play his first game since suffering a foot injury on July 29.

"He has come on a little bit quicker than probably a few would have thought," Port midfielder Connor Rozee told reporters.

"He has been an integral part to our football side over the last few years now ... he'll definitely be a big chance, he was moving pretty well today."

Dixon's return would boost the Power amid doubts over fellow key forward Todd Marshall, who walked laps at training.

Marshall has been battling a hip injury - he missed the last home and away match and returned to face the Lions but was unusually inaccurate in front of goal.

"He has been a little bit sore over the last few weeks ... (but) we have got full confidence in him," Rozee said.

"One of the hard parts about football is battling through injuries - when you're out there, people probably just expect you to play like you're 100 per cent."

Port players rapidly moved on from their 48-point away loss to Brisbane in a qualifying final at a Monday meeting.

"Finals football, you don't really have that time to dwell on the previous week," Rozee said.

"The whole meeting was pretty much focused on how quickly we can move on because we have earnt the right to have a second chance at this.

"And we're still in such a privileged, great opportunity to put ourselves in a prelim final.

"There's not too much to be walking around sulking about ... there's a lot of teams that are at home right now that would kill to be right where we are at this point in time.

"There's no dwelling on the weekend, that's for sure."

Port belted the Giants by 51 points in round 22 at Adelaide Oval, the only clash of the clubs this season.

"We have already looked at a few things from last time we played them," Rozee said.

"I definitely don't think it's going to be a blowout like it was last time, they have been in great form.

"We just can't wait to get to Adelaide Oval, that's the main thing - we bring what we bring no matter who we face and we know that stacks up against the best teams.

"So play four quarters of our football and I'm sure we will come away with a win."
