"It's a blow, we just got him (Ralls) back and now he will miss a period," Bluebirds manager Neil Harris confirmed.
"It is a shame as we just got him back and I have been clear he is going to be an instrumental player in my side."
Cardiff have also been dealt a further blow with defender Joe Bennett suffering an Achilles injury.
"Joe went down in training yesterday (Friday)," Harris added.
"Will he be ready for the Christmas period? I don't know. We will assess him again. The Achilles is a fatigue injury."
Jazz Richards replaced Bennett today for a rare appearance in the first team. It was his first this season.
