Justin Westhoff and Sam Mayes are among a number of players in the mix pushing for selection.

PORT ADELAIDE will be forced into at least one change at the selection table for Monday night’s season-ending encounter with Collingwood.

A hamstring injury to defender Tom Clurey means he won’t travel to Brisbane to tackle the Pies but he is expected to be fit to play in the club’s first final.

It means the door is open for someone to show they have what it takes ahead of the AFL finals.

Experienced campaigner Justin Westhoff headlines a list of players in the mix for selection after missing the last two games but impressing in match simulation sessions involving Hawthorn and Adelaide.

And there are a host of defenders pushing their claims with backline mentor Brett Montgomery on Tuesday flagging Jarrod Lienert, Miles Bergman, Jack Watts and Joel Garner as the most likely, along with utilities Sam Mayes and Cam Sutcliffe, who have each shown this season that they can play defensive roles if needed to.

Small forward Boyd Woodcock has been an emergency in recent matches and is a chance for a recall if the selectors elect to shuffle things around.

Port Adelaide will on Sunday evening name its side to tackle Collingwood, with first bounce at the Gabba at 7:15pm AEST / 6:45pm ACST on Monday.
