"The Carlton Doctor has monitored Chris's progress this week and while he has continued to improve he has not recovered sufficiently to play in tomorrow's game," said Carlton coach Brett Ratten.
"Medical tests conducted during last week's game, following the heavy collision in the first quarter, indicated Chris was fit to continue during the match and the medical team regularly monitored him throughout the game. Unfortunately his symptoms deteriorated after the game. The medical team have confirmed that Chris playing out the game against Essendon has had no bearing on his availability for selection this week," Ratten added.
Darren Pfeiffer will replace Judd in the Carlton squad for tomorrow's game.
