Hawthorn defender Brent Guerra might make Saturday's premiership his last AFL game.

A year after missing out on the finals series with a hamstring injury, the 31-year-old was part of the Hawks team that beat Fremantle in a rugged grand final.

It was the second premiership for the former Port Adelaide and St Kilda backman, who was also a member of the victorious 2008 Hawthorn team.

Guerra now must decide whether he wants to put his battered body through another season.

"I will wait until next week and then make a decision," he told Channel Seven.

"I'm 50-50 at the moment, but we'll wait and see."

Guerra played 19 games this year as the Hawks carefully managed his workload.

He admitted after the grand final win that last year's injury had played on his mind.

"Even this year, in the back of my head, it was 'I hope I don't do that hamstring again', because I want to play in a successful side," he said.

"It's always in the back of my mind, but here we are."

Teammate Sam Mitchell wants the tough defender to keep playing.

"You have to love the way Gooey goes about his footy," Mitchell told Channel Seven's Game Day.

"He gets the job done, there's never any fanfare with him.

"Hopefully he continues to play on - there's a spot there if he wants it.

"He's one of those blokes you just love running out with because you know what you're going to get every week.

"If you ever need a bit of physical help, he's there to give it to you."
