West Coast have delisted Daniel Venables but are committed to helping the AFL premiership forward recover from his brain trauma injury.
The 22-year-old has not played since May last year, when he received a head knock in a collision with Melbourne's Tim Smith.
The significant impact resulted in ongoing concussion symptoms and Venables has still not received medical clearance to return to football action.
Eagles list manager Darren Glass said the club was hopeful Venables may one day be able to add to his 21 AFL matches with them.
"We remain committed to helping Dan strive to play senior football at our club again," Glass said.
"But, as it has been since the incident, our primary focus remains Dan's health and wellbeing.
"We will continue to explore with the AFL the options available to us to facilitate Dan's return to senior football with us as soon as he is medically cleared to do so."
West Coast reportedly requested a list exemption in October to keep Venables at the club.
Meanwhile, Collingwood defender Tom Langdon has retired because of a chronic knee injury.
The 26-year-old intercept specialist has not played since May last year and had been in talks with the Magpies over the final year of his contract for some time.
He was officially delisted on Monday.
Langdon played 89 games for Collingwood and was a star in the club's heartbreaking 2018 grand final defeat to West Coast.
"Tom played some wonderful football for Collingwood and it was a sad day when the reality of his premature retirement arrived," Magpies football manager Geoff Walsh said.
"We saw him work incredibly hard to get back.
"He pushed himself through so much pain to keep his hopes of a comeback flickering.
"Given his talent and application, his finish is a cruel football story.
"We're all confident that Tom will make a success of the next phase of his life and we wish him well."
Respected club administrator Walsh has also announced his decision to retire.
The 64-year-old will step away from his position at Collingwood in December after 36 years in the AFL-VFL system, including stints with Fitzroy, Carlton and North Melbourne.
