Carlton key-forward Levi Casboult could be sidelined for up to eight weeks due to a leg injury, meaning he’ll miss Saturday night’s clash against North.

Casboult suffered a hairline fracture in his left leg in the opening minutes of the Blues’ win over Port Adelaide.

He does not require surgery, but is still set for an extended spell on the sidelines.

Matthew Kreuzer, Patrick Cripps, Lachie Plowman and Ciaran Byrne all required attention during Carlton’s fourth win in succession.

Kreuzer hobbled off in the second term with what looked like an ankle concern, but later returned to the field.

Cripps hurt his right knee late in the third quarter, but also came back on in the final term.
