PORT Adelaide midfielder Karl Amon says the Power's onball brigade needs to help makeshift ruckman Jackson Trengove to stop Melbourne's hit-out king Max Gawn dominating the stoppages.

Amon has designed the Power's indigenous jumper it will wear for Saturday night's clash with the Demons in Alice Springs.

The jersey is called "Bambara", which means ''journey'' from the Jandai language of Amon's Noonuccal people from North Stradbroke Island in Queensland.

Eight small circles on the outside represent the eight indigenous players on the Port Adelaide list, while the big circle represents the club, players, coaches, staff and supporters.

Amon started designing the jersey in December last year, consulting with his mum about how to best represent his people.

"We bounced ideas off each other and she found out the language from my people at North Stradbroke Island,'' Amon told AFL.com.au.

"As a young kid, I grew up waiting for Indigenous Round waiting to see what jerseys the clubs were wearing.

''For me, to design one and wear it is a really proud moment for me.

''I'm sure this will be hanging up in my house sometime soon.''

Amon's teammates Jake Neade, Chad Wingard and Brendon Ah Chee have had the honour of designing the Power's indigenous jersey in recent years.

The Power are keen to bounce back from last weekend's eight-point loss to West Coast, but face a Demons side that also has finals aspirations.

Gawn's dominating work in the ruck is a key behind the Demons' success, averaging nearly 40 hit-outs per game.

In contrast, Trengove is averaging six hit-outs per game as a capable fill-in for the injured Matthew Lobbe, while Charlie Dixon and Justin Westhoff will also pinch-hit in the ruck.

"Gawny is in All Australian form this year so it's going to be really tough for Jacko,'' Amon said.

''We just rely on Jacko to provide a really good contest each week.

''It's up to us midfielders to hunt the ball on the ground and fight it out from there.''
