"After months of consideration I have decided to officially retire from the NRL and move back home," Elgey wrote on his Instagram account. "I just know deep down I don't love it like I use (sic) to and when you lose that it's very hard to keep doing it at a high level."

Elgey debuted for hometown club Gold Coast in 2015 but the Australian Schoolboys representative's career stalled when he suffered an ACL injury in pre-season training before the 2016 campaign.
