Andrew Walker will line up for his swansong on Sunday at the MCG against St Kilda, with Dale Thomas also set to return from injury for the clash. 

The pair have been named in the Blues’ extended squad alongside Mark Whiley.

Walker announced his retirement earlier this week and will hang up the boots on Sunday after 202 games for the Carlton Football Club.  

The Saints have added experienced key defender Sam Fisher, Cam Shenton and Jason Holmes to their extended squad.

Both clubs will name their final 22-man sides on Friday evening.
