Melbourne’s Kade Kolodjashnij is currently on a modified program following another concussion setback.
Kolodjashnij, 24, suffered a head knock in a training incident late last year with the Demons reluctant to set a timeframe on a return.
The former Sun hasn’t played since Round 3 last year and was restricted to just two games in his first season in the red and blue.
A head knock in the VFL ruled him out for the remainder of the 2019.
"As a club, we are respecting Kade's history of concussions and being very cautious with his rehabilitation,” Melbourne GM of Football Josh Mahoney told afl.com.au.
"His program has been developed by medical experts and he is showing signs of improvement.
"At this stage, we have not put a timeframe on his recovery and subsequent return to football."
Kolodjashnij and Steven May were traded to Melbourne from Gold Coast in exchange for pick No.6 in the 2018 trade period.
