St Kilda will be forced to make at least two changes ahead of the clash with West Coast in Perth, with experienced stars Nick Riewoldt and David Armitage sidelined due injury.

Riewoldt hyperextended his knee late in the loss to Melbourne last Saturday night, while Armitage has pulled up with some groin soreness and won't travel west.

Budding key forward Paddy McCartin could return to the senior side after he was a late withdrawal from the clash with Melbourne.

The 20-year-old kicked three goals in Sandringham’s practice match against Port Melbourne on Sunday, before sitting out the final quarter.

Dual All-Australian Leigh Montagna should return for the trip to Western Australia after he played his first game for 2017, collecting 18 disposals for the Zebras.

The 33-year-old half-back flanker missed the Saints’ entire JLT Community Series after suffering a calf strain.

Opening round emergencies Blake Acres and Billy Longer will be in the selection mix after St Kilda’s engine room failed to fire against a dominant Melbourne midfield on the weekend.

After playing 16 games in 2016, big-bodied midfielder Acres could return to his home state after he was one of Sandringham’s prime movers on Sunday. While Jack Sinclair was another onballer to press his case for a senior berth at Trevor Barker Oval.
