Port Adelaide skipper Travis Boak will evaluate at the end of the season if he wants to head into his seventh season as the Power’s captain.

But for now, his priority is making sure his side are a sure thing for September.

The eighth-placed Power are experiencing a patch of low form, having lost four of their past five games, and will be coming up against finals aspirants Collingwood at the MCG on Saturday.

The Power hold a host of  injury concerns, including ruckman Paddy Ryder (hip flexor) winger Jared Polec (hamstring) and defender Dan Houston (neck) in doubt.

Boak is the Power’s longest-standing captain having taken over Dom Cassisi in 2013.

Vice-captain Ollie Wines is the most likely choice to take over from Boak after he signed on till 2022.

Boak, 30, has played in 241 games for the Power, and has signed on until the end of next season.

“Ollie’s been outstanding all year as vice-captain, along with the rest of our leaders,” Boak told AFL.com.au.

“I’ve enjoyed the challenge I’ve had this year and I’m still hoping to have a few more weeks to go this year as captain.

The Power led the game against the West Coast Eagles for the most part, before leaking goals, allowing the Eagles to steal victory.

Boak said the players watched over the final quarter of the game and took away some valuable lessons from it.

“There were certainly different challenges in the game we didn’t handle well enough,” he said.

“We probably would have controlled the ball a lot more and there were options we should’ve used.

“That last play, there was a lot of yelling going on, the crowd was really loud.

“The communication wasn’t right and we could’ve done it a lot better.”

The Power will play a more mobile and medium-sized forward line against the Magpies with key forward Charlie Dixon set to miss the rest of the season with a broken leg.

“You can’t really replace Charlie, so we’ll have to move a few things around,” Boak said.

“We’ve still got a very dangerous, potent forward line with Robbie Gray, Chad Wingard, Jack Watts, Sam Gray and Aidyn Johnson.

“There’s some quick, dangerous guys down there that will cause problems for opposition sides, so we’ve got to make sure we get it in there enough.”

The Power’s inconsistent attack has been viewed as the reason for their breakdown in the past month.

They’ve scored an average of 67.4 points per game in rounds 17-21 in contrast to 86 points from rounds 1-16.
