Essendon have been forced to activate their medical substitute with Nik Cox being forced to exit the game with an ankle injury.

The Bombers headed into the halftime break 14-points behind the Western Bulldogs and after a sloppy first half.

Dylan Shiel who was omitted from the 22 this week now enters the game.
