St Kilda are reportedly showing interest in delisted Tiger Sydney Stack.

Stack managed 35 games in four years at the Tigers before the club confirmed the young utility would not be offered a new deal for 2023.

According to The West Australian, it is believed that Stack and the Saints have been engaging in regular talks over the past weeks, and the possibility of the 22-year-old joining St Kilda is a live chance given the club has two free list spots for the Supplemental Selection Period.

Stack has been training with the Perth Demons in Western Australia since leaving Punt Road, which looms as a backup plan for 2023 if he fails to find a spot on an AFL list.

The Saints are currently trialling former Blue Liam Stocker and ex-Essendon defender Josh Eyre at Moorbbain, with the discarded duo pressing their case for an AFL reprieve.

Controversial AFL media figure Kane Cornes thinks the Saints should use an SSP spot on retired Eagles forward Josh Kennedy, due to the injury to Max King.

“I've got a task for one coach, and that is (to) get on the phone and get Josh Kennedy out of retirement. That coach is Ross Lyon,” Cornes said on SEN

“They have to play finals, otherwise there's egg on the face of those who have made this decision to resign and sack Brett Ratten.

“Kennedy, clearly it's his body and he's spoken about his debilitating knee injury that he's got. But if the call hasn't been made yet, it needs to be made. He kicked 37 goals from 15 games last year."

The SSP window is scheduled to run until February 15, while the Western Bulldogs (Oskar Baker), Brisbane (Conor McKenna) and North Melbourne (Liam Shiels) have confirmed signings for 2023.
