CARLTON has suffered a significant blow with emerging defender Caleb Marchbank set to miss the next four weeks with an ankle injury.
Marchbank came from the ground midway through the first term of the Blues' 24-point loss to Collingwood last Friday night, returning to play some of the second quarter before sitting out the entire second half.
Carlton football manager Andrew McKay told the club's website Marchbank's rehabilitation would be managed conservatively.
"He obviously didn't play the whole game and went off injured with that ankle. There's not a whole lot of damage there thankfully but he will be out for around four weeks," McKay said.
"[His return date] will depend on his level of pain tolerance when he makes his way back into the skills program."
