A trio of key AFL performers will need to prove their fitness before Yartapuulti's (Port Adelaide) clash with Richmond, while Junior Rioli is set to return after serving a two-week suspension.

Tests have cleared former Power skipper Travis Boak of serious injury after he was subbed out with a knock to the ribs against Melbourne.

It was a similar story in the pre-season, as the 34-year-old sustained heavy bruising around his ribs and lung area, but wouldn't show major damage. Boak would go on to miss the season opener.

He will be a test for this weekend's performance.

Power forward Charlie Dixon could be a welcome boost to Port Adelaide's undermanned attack, as he seeks to return from a quad injury.

The spearhead is hopeful of an AFL return this week and will be assessed before the final teams are named on Friday.

Also sidelined, Todd Marshall could bring the Power's forward line to full strength if he clears a final concussion test.

The 24-year-old has suffered head knocks in consecutive AFL appearances, but is expected to return this week when his concussion protocol period is completed.

After a breakout 2022 season, Marshall has failed to have the same impact this year. His eleven goals have been timely, but his dominant forward play hasn't recurred this season.

With Mitch Georgiades out for the season with an ACL tear, Port Adelaide has relied heavily on talls Jeremy Finlayson and youngster Ollie Lord, who made his AFL debut in Round 6.

Rioli, having been suspended for two weeks after a hit on Bomber Jordan Ridley, is another known goalkicker set to enhance the Power's scoring ability.

After arriving from West Coast in the off-season, the 27-year-old has slotted ten majors in eight matches at Yartapuulti.
