Henderson played in the Cats’ preliminary final loss to the Tigers after Tom Hawkins was suspended but played much of the 2019 season in the VFL due to a mixture of form and injuries.
In the match that now looks to be his last for the club, Henderson kicked a goal and had five disposals and five marks.
Henderson is currently overseas on holiday and has not commented on the situation.
Henderson, who has formally worn Lions and Blues jerseys, played 54 games for the Cats since joining the club in 2015. He has played 171 AFL matches since he was drafted in 2007 by the Lions.
