PORT Adelaide's Jarman Impey could be on the move despite having a year to run on his contract.  

The dashing defender, who is signed until the end of 2018 after agreeing to a long-term extension in 2015, has been a regular member of Port's line-up in his four years at the club.  

However, AFL.com.au believes the Western Bulldogs and Hawthorn are among the clubs interested in luring the Victorian back home.  

Impey played 20 games for the Power this year, including their elimination final loss to West Coast, and averaged 11 disposals.  

He missed the opening round against Sydney after an off-season car crash, when he left the scene and then handed himself into police the following day.  

Impey joined Port with pick 21 at the 2013 NAB AFL Draft, and has impressed as a powerful and speedy half-back.  

Port could be set for a busy exchange period, with Ken Hinkley's men linked to Brisbane Lions free agent Tom Rockliff. The Power also met with Melbourne forward Jack Watts last week, with the former No.1 pick appearing set to depart the Demons, and they have been linked to Geelong midfielder Steven Motlop too.  

Port is also expected to lose Jackson Trengove as a free agent, with the defender/utility set to join the Western Bulldogs.  

The free agency period begins next Friday, October 6, before the trade period opens the following Monday, October 9 and runs through to Thursday, October 19.  

With the likes of Dustin Martin and Josh Kelly already re-signed despite speculation on their futures, most clubs believe the biggest surprises set to come in trade period will be contracted players moving clubs.
