PORT Adelaide veteran Kane Cornes will play on in 2015 for a 15th season in the AFL after signing a one-year deal.

The 31-year-old has played a club record 285 games since being drafted by the Power with pick No. 20 at the 2000 NAB AFL Draft.

Cornes said both he and Dom Cassisi, who retired after last Sunday's win over Melbourne, had spoken to coach Ken Hinkley about their futures earlier in the season.

The difference between the pair was that while Cassisi's body struggled to keep up with the frenetic pace of modern football, Cornes' felt fine.

"Probably about the same time I spoke to Ken in round nine, Ken spoke to Dom as well, so I was aware of that and at that stage Dom thought he was struggling a little bit to get up for games," Cornes said.

"Luckily for me I've had a pretty good run with my body and haven't missed too much training, I've done all the pre-season and haven't missed a game.

"As you get older it does get a little bit more difficult but there's been nothing to indicate to me that I can't compete at the level.

"As soon as that does happen, probably like Dom, I'll be the first to put my hand up."

Should he reach the 300-game milestone next season, Cornes would become the first to play 300 for the Power, with the club's only other triple-century player, Gavin Wanganeen, having spent several seasons at Essendon.

Cornes has displayed incredible durability over the course of his career and is on track to play at least 20 games in a season for the 11th time. 

He is a renowned training fanatic and credited his "crazy" regime for his longevity.
"All I can do is prepare and train like I have done and that's what got me in the position to be able to play so many games," he said.
"So that's what I'll continue to do. It's a formula that I've done for 15 years so I'll keep doing it.
"I'm probably still as crazy as I ever have been in terms of doing sessions in the off-season."
The four-time best and fairest also played down the club's recent patch of poor form, insisting the group would return from its bye refreshed and ready to attack the top four.

Port has lost four of its last six games, falling from first spot to fifth along the way.
But Cornes said lulls in a season had to be expected from such a young group and backed them to respond during the run home.
"We've been a bit flat the last three or four weeks but that happens to a young side. It's a marathon this season and for a young group that hasn't gone through that yet, it's challenging," he said.
"Injuries play a part. You take your two key backs out of any side in the competition and it's going to hurt you, so we look forward to getting some guys back.
"If you finish top four you're in a pretty good position to challenge [for the premiership] so that's got to be our aim."
