THE WESTERN BULLDOGS have lodged paperwork to claim Jackson Trengove as a restricted free agent.

Port Adelaide now has three days to consider the offer made by the Bulldogs, and can match the offer should it wish to retain the 26-year-old.

Trengove has played 153 games for the Power since joining the club in 2008, and won the club's John Cahill Medal in 2011.

Trengove played 19 games for Port in 2017.
