Port Adelaide have dipped into the delisted free agent pool, and have signed former Gold Coast defender Trent McKenzie.

The Power have lodged paperwork for the 25-year-old, who played 106 games for the Suns.

McKenzie played in Gold Coast's inaugural AFL game against Carlton in round two, 2011, and played 21 games for the Suns in their first season.

The running defender quickly gained a reputation for being one of the biggest kicks in the league, and was dubbed 'The Cannon' early in his Gold Coast career.

In his first five seasons with Gold Coast, McKenzie played over 16 games per season, although he failed to fire in recent times for the club.

He played just seven matches in both 2016 and 2017, and will now join the growing list of ins at the Power.

McKenzie will join Tom Rockliff, Steven Motlop and Jack Watts as inclusions this off-season, as the Power look to build on their elimination final loss to West Coast next season.
