Collingwood veteran Levi Greenwood is understood to be facing an uphill battle to continue his career in the black and white.
According to AFL Media's Mitch Cleary, the seasoned midfielder is continuing to suffer from concussions symptoms sustained during his side's loss to West Coast over a month ago.
Greenwood is set to visit a specialist in the coming days to better understand where his immediate health and playing future lies.
Currently off-contract at the Holden Centre, Greenwood's future remains up in the air as he looks to overcome the constant concussions issues sustained in Round 5.
The 32-year-old has played 86 games for the Magpies since switching from Arden Street at the end of the 2014 season and was limited to just six games last season due to injuries.
Greenwood is one of several key Magpies battling setbacks in 2021, with Jeremy Howe, Taylor Adams and Jamie Elliott all currently sidelined.
The latter duo are expected to return to the the selection frame in the next two weeks, while Howe's season remains in doubt after further delays in his recovery from a hamstring injury also sustained in the Eagles clash.
