OUT-OF-CONTRACT Port Adelaide pair Paddy Ryder and Sam Gray are poised to depart the Power after indicating their desire to explore other options for 2020. 

The Power confirmed on Tuesday night that the duo was looking elsewhere, while AFL.com.au understands midfielder Karl Amon is weighing up interest from Melbourne and St Kilda. 

Ryder, 31, has been seeking a two-year deal to extend his career, but is believed to have only been offered one year to remain at Alberton. 

It has opened the door for outside interest from St Kilda which is in need of a back-up ruckman, while Essendon has registered interest after early calls from Greater Western Sydney.

"Paddy has been a valued and much-loved member of our playing group since he came to Port Adelaide,” Power coach Ken Hinkley said.

"He's been a fantastic servant of the club, a best and fairest winner and a terrific teammate and person to have around.

"Based on where the club's ruck stocks are at, both Paddy and the club have reached a mutual decision that it would be best for him to explore his playing options."

Ryder has recently fallen behind Scott Lycett and Peter Ladhams in the Power's ruck division.

Meanwhile, despite playing 20 games this season, Gray was given no assurances of a long-term stint at the Power and will instead search for greater security at a rival club.

Carlton, who has openly admitted its need for a small forward, is among the interested parties in the 27-year-old.  

"Sam has always represented the Port Adelaide Football Club at SANFL and AFL level with pride and passion, and he has made a significant contribution to the club," Hinkley said.

"From a list management perspective, we have had ongoing discussions with Sam's management and agree that it is in the best interests of the club, and of Sam, to give him a period of time to explore opportunities to play elsewhere in 2020."

It comes as Amon mulls over a move away from South Australia despite a three-year offer on the table from the Power.

The 24-year-old played 17 matches this season to forge his place in the Power's best line-up, just 12 months after failing to find a home in Victoria and break his contract for 2019. 

The Power still holds hope he will re-commit to the club. 

Veteran utility Justin Westhoff is expected to trigger a one-year extension to remain at the club, while the Power are also closing in on securing the signatures of Riley Bonner and Kane Farrell. 

Midfielder Sam Powell-Pepper, who remains contracted until 2020, is also set to receive interest after finding himself on the outer in the second half of 2019.
