The 22-year-old amassed 12 appearances in the blue and white hoops across the past three seasons, with two of his three matches this year coming as the medical sub.
The limited opportunities have since seen Constable delisted from Geelong, however the Cats have flagged they could look to recruit the Sandringham product following the National Draft should no keen suitors emerge.
With the tall onballer now set to assess his options in the open market, we look at the potential suitors outside of the Cattery that should be keeping an eye on Charlie Constable.
The Magpies have quickly looked to transition their list demographic and acquire younger, cheaper options as they embark on a new era under senior coach Craig McRae.
Collingwood were able to utilise a plethora of key names to best gauge their future assets, recording the most debutants for the season with nine fresh faces pulling on the black and white.
Not every emerging rookie was able to impress on the big stage, with the Magpies even cutting ties with midfielder Jay Rantall at season's end.
Collingwood also bid farewell to big-bodied onballer Brayden Sier, with McRae's midfield depths now placing more focus on recruit Patrick Lipinksi and incoming father-son prospect Nick Daicos.
The Magpies should perhaps look toward Constable as another inclusion into their engine room, with the VFL ball-magnet proving to be well above the standards of the reserves tier.
As Collingwood look to shuffle through youthful talent in hopes of finding a diamond in the rough, Constable may just be the undervalued option that is cheap enough to warrant a rookie contract at the Holden Centre.
