SWINGMAN Aaron Black is the first casualty of what shapes as an aggressive off-season for Geelong with the ex-Kangaroo delisted by the club on Monday.

Black, 28, ruptured his ACL against his former side North Melbourne in round 12 this year and missed the remainder of the season.

Arriving as a forward at Geelong ahead of 2017, Black moved into defence early this year in an attempt to earn a senior spot following injuries to Harry Taylor and Lachie Henderson.

Following four games as a forward in 2017, Black managed three games in 2018.

The West Australian played 50 games for the Roos between 2011-2016, including a breakout season with 33 goals in 2013.

Rewarded with a four-year deal, Black continued his rise playing all 25 games in 2014 as the Roos lost the preliminary final to Sydney.

Restricted to three matches in 2015, Black failed to play a senior game in 2016 before he was traded for a fifth-round selection, three years into his four-year deal.
