Freeman and Woodville-West Torrens star James Tsitas were competing for the last remaining spot on the Suns' list this pre-season, with the latter officially being added to Stuart Dew's ranks last week.
The decision has left Freeman to continue his search for an AFL lifeline, having been delisted by St Kilda at the end of the 2018 season.
The 26-year-old played just the two AFL games across five years in the system, having endured an injury-riddled career across stints with the Saints and Magpies.
A stellar VFL campaign with the Frankston Dolphins placed Freeman back on the radar of AFL clubs, however a second chance in the league has so far failed to transpire.
According to 7 News Adelaide, Freeman is now set to link up with the Crows' reserves for the 2022 season following his missed chance with the Suns.

Adelaide finished third last in the SANFL last season, amassing a 5-13 record to remain just two points outside of finals.
A move to the Crows could see Freeman use his next career chapter as a potential springboard back into the top flight, with the AFL understood to be weighing up a top-up player pool should clubs require further squad depth given the impacts of the COVID-19 pandemic.
Adelaide are yet to confirm Freeman's signature, while Louis Sharrad, Isaya McKenzie, Jacob Templeton, Josh Smithson and Sam Breuer have already joined the Crows ahead of 2022 season.
