PORT Adelaide defender Matthew Broadbent will miss two weeks with a hamstring injury, but is expected to be available for the club's final game of the JLT Community Series.

The Power has named a strong squad for their opening game of the pre-season competition against St Kilda at Etihad Stadium on Thursday night.

But several experienced campaigners including Broadbent, three-time best and fairest Robbie Gray and midfielder Matthew White won't be making the interstate trip.

Gray could play the Power's final two games of the pre-season, while White is being troubled with a calf injury.

Broadbent was restricted to running laps at Alberton Oval on Wednesday morning.

"He might be a couple of weeks, he's got a bit of a hamstring issue at the moment," midfield coach Michael Voss said.

"The great thing with (Broadbent) is that this is the first rehab session that he's ever had in his career.

"You can guarantee one thing – he won't be there that long.

"He's a true pro and he'll be back pretty soon."

Gray completed some short sprints at training and also didn't play in last Friday's intraclub trial.

"Robbie is just a little bit sore at the moment," Voss said.

"I expect he'll probably be right to go next week … or certainly the week after."

White had a wretched run of injury last year.

The 29-year-old tore his pectoral muscle in the opening quarter of the club's round one clash with St Kilda before fracturing his cheekbone in the SANFL.

"He's going to be a week to week proposition at the moment," Voss said.

"He's had a bit of a start, then stopped, then started and stopped again.

"We've just got to make sure we've got his body in the right shape."

Winger Jared Polec left training with an ice pack on his back, but Voss expected him to be right for the club's opening pre-season game.

"He'll play," Voss said.

"Most of the guys that end up going out there over the next couple of weeks, we'll just manage their minutes to get them right for round one."

Voss said it would be a similar situation with ruckman Patrick Ryder, who is set to play his first game since 2015, and key forward Charlie Dixon, who had ankle surgery in the off-season.

"In (Ryder)'s situation, being 12 months out of the game, continuity is a good thing," Voss said.

"Some of them might argue some of the training sessions they do are a little bit harder.

"We feel the connection among the group is important and these times are pretty valuable to put a few things in place."
