The AFL careers of Port Adelaide's most experienced duo appear over, with Warren Tredrea to retire and Chad Cornes contemplating his exit.

Tredrea is expected to announce his retirement on Tuesday.

And Cornes will have season-ending surgery on a broken finger, an operation further clouding his future.

Tredrea has played a club record 255 matches but has missed the past 10 games after having ankle surgery.

The former Power captain is the club's most decorated player, with four club champion awards, four All Australian jumpers and seven leading goalkicking gongs.

Tredrea turns 32 in December and had been attempting a comeback from his ankle injury.

But with Port's caretaker coach Matthew Primus embarking on a board-endorsed youth policy, Tredrea is believed to have decided to quit.

Primus has also overlooked Cornes, who turns 31 in November, for AFL selection in the past two weeks.

Cornes broke the little finger on his left hand while playing for Glenelg in the SANFL on Saturday.

A club spokesman said Cornes was expected to miss at least a month after having surgery on Monday night.

With only five AFL games remaining, the dual All Australian's season is shot.

Cornes, who is contracted until the end of next season, has been shunned by Primus since being suspended for one match in Port's round 14 loss to Fremantle.

But Primus has denied already deciding the premiership player's fate.

"By no means has he already been stamped away from this club," Primus said last Friday.
