Carrazzo left the field in the second quarter of Saturday's match against Fremantle.
Carlton's General Manager of Football Andrew McKay says scans have revealed Carrazzo has a calf strain.
"Andrew sustained a strain to his calf muscle, which is very disappointing for him. He'll be out for two weeks at this stage and we'll see how he progresses."
In better news for the Blues, Jarrad Waite has returned to training and is hopeful of playing in Saturday's clash with the Western Bulldogs.
Meanwhile Andrew Collins, David Ellard, and Andrew McInnes will all face fitness tests and may be available for selection.
