Fremantle defender Luke McPharlin is set to play on in 2015.

The All Australian backman, who has played 238 games in 15 seasons in the AFL for Hawthorn and Freo, has committed to going around again next season.

Fremantle general manager of football operations Chris Bond said McPharlin's new contract would be finalised within a week.

"Yeah we do (expect him to play on)," Bond told NAB AFL Trade Radio.

"He's certainly got his head around doing that.

"There's been a lot of talk about him being 33 in December, so we're very conscious of a lot of work and rigour going around the physical side of things.

"But knowing Luke as well as we do and because he's held in such high regard, a lot of it is around the mental side of things and he's in."

Despite reports to the contrary, Bond revealed Freo had not spoken to out-of-contract Essendon midfielder Ben Howlett.

Should Howlett leave Essendon, it is understood Carlton is the frontrunner to secure his services.

Bond also said ruckman Zac Clarke was a required player and would not be put on the trade table this week.

As expected, Fremantle have also said they will not pursue Mitch Clark in this week's NAB AFL Trade Period.
