Cutting an injured player who is still rehabbing doesn't fit in with our list management culture at all. It makes a lot of sense to delist him as he was the last player that could afford such a major injury but it won't happen.
Plenty of teams do it.
Geelong delisted Gary Rohan only 2 weeks post a serious brain injury.
By having him on the list another 12 months you are just delaying the inevitable imo.
