Port Adelaide key forward Jay Schulz will be tested at training this week to determine a possible return against Fremantle for Saturday's round 22 clash.

The Power hosts what looks to be an undermanned Fremantle on Saturday, with Schulz to be reviewed to return from the back injury that kept him out of Port’s win over Gold Coast last weekend.

Who's in the mix to face Port?

“Schulzy missed due to his back and we’ll see how he goes at training,” Port physio Darren Burgess told portadelaidefc.com.au.

Fremantle play Port Adelaide on Saturday 5 September. Bounce down is 1.50pm local time.
