THREE CHANGES have been made for Port Adelaide's Round 17 team with Brendon Ah Chee and Paul Stewart omitted. 

Nathan Krakouer will miss with a hamstring injury.

INJURY: Krak strains string with last kick of day

Selectors have brought in three midfielders to replace them, with hard-running Matt White and Sam Colquhoun named on the interchange along with big-bodied midfielder Andrew Moore.

White's selection comes off the back of an extended period on the sidelines rehabilitating a hamstring injury. 

Moore had 21 hitouts in a rare role playing as Port Adelaide's third-man up in last weekend's 41-point SANFL win over Woodville-West Torrens, while Colquhoun has been solid for the Magpies over several weeks.

PREVIEW: Power v Dons

Jonas makes Port SANFL debut

Tom Jonas will return following his omission a fortnight ago through the SANFL.

It will be the medium defender's first state level game since 2012 and comes as youngsters Billy Frampton and Jesse Palmer return to the side.

Jonas is a chance to play against his brother Sam, who is a forward for the Double Blues.

Luke Reynolds has been omitted from the League side and will go down to the Academy team for the early game at Unley.
