The news comes after Siposs returned to Melbourne after playing 32 NFL games for Philadelphia, including a Super Bowl loss to the Kansas City Chiefs earlier this year in Arizona.
The final member of Hawthorn's coaching panel for 2024, Siposs is no stranger to being a coach, having spent time coaching football at Brighton Grammar School and Hallam Senior Secondary College in the past.
“We believe our entire coaching team is well balanced to continue developing our young list and giving them every opportunity to succeed,” Hawthorn's General Manager of Football Rob McCartney said in a club statement.
"Arryn joins our club with great experience and perspective following exposure across two high performance environments, in the AFL and NFL, which we believe will benefit our program immensely. We see him being a great fit for our talented young list and helping develop players, both on and off the field.
“Through both our AFL and AFLW program David has demonstrated he has a bright future as a young coach. Stepping into a full-time role with our AFL program will allow him to deepen his relationships and development opportunities with our younger players.”
Hickmott will join as the forward's coach after Chris Newman's departure to the Richmond Tigers, and Mackay will join the AFL program full-time as a development coach. This comes after he split his time between the men's and women's programs last season.
Zane Littlejohn has been selected as the VFL coach of the Box Hill Hawks and will also find himself as a development coach for the Hawks AFL program. Andy Collins will remain as the Head of Development at the club - a position he has been in for the past two seasons.
