Cripps will be assessed during the week to find out the severity of his injury.
Melbourne midfielder Jordan Lewis struck Cripps in the head with his left hand during the third quarter, and was subsequently suspended on Monday for three matches, after medical reports from Carlton were used in the MRP’s final decision.
“Patrick had scans last night which confirmed a small hairline fracture in his jaw,” Carlton Head of Football McKay said.
“Given his jaw is stable and not displaced, we will assess him further over the coming days to determine whether he will be available to play this Sunday against the Bombers.”
The 22-year-old was one of Carlton’s best against the Demons, collecting 29 disposals and 10 clearances in the 22-point loss.
