Port Adelaide may have found the missing piece to their premiership credentials.

Former Collingwood premiership defender Tyson Goldsack could make a shock return to the AFL after nominating for the AFL Draft and Rookie Draft.

The 33-year-old retired at the end of 2019 after 165 games for the Magpies. His last game was the 2018 Grand Final, which the Magpies lost by five-points to West Coast.

As reported by Reece Homfray in The Advertiser, Goldsack could provide much-needed experience and depth to the Power's key defensive stocks.

Trent McKenzie was forced to play as an undersized defender on Tom Hawkins and Tom Lynch in the finals.

McKenzie only conceded one goal across the two games but the damage could have been worse had Hawkins kicked straight instead of 0.5 in the qualifying final.

Goldsack initially signed to be the captain of Port Adelaide's SANFL team in 2020, but the club had to pull out of the competition due to AFL COVID-19 protocols.

He then worked with Power defensive coach Brett Montgomery during the season and his primary role in 2021 will be to provide leadership for Port's SANFL team.
