The AFL has introduced a new signing period for players overlooked in the draft and rookie draft. One is the supplemental selection period (SSP) between December 1 and March 15, after all the drafts are over. The SSP is for state league players who miss out on the draft as well as players recently delisted by their clubs. To be eligible, players must have previously nominated for the national draft or previously been on an AFL club list.
Just before the AFL deadline of October 31 for club list submissions, nine clubs delisted players. Several clubs also signed delisted free agents.
Hawthorn delisted Will Langford, Brendan Whitecross and Kieran Lovell. Langford played 72 games for the Hawks including the 2014 premiership but managed only six games in 2018. Whitecross, a life member of the Hawks, played 111 games since 2007 in an injury-plagued career. He did play in VFL team Box Hill's 2018 premiership team.
