Ferguson says that the 27-year-old's ankle injury will be assessed by the United medical team on Sunday to determined if he will be fit to play in their Champions League Group H clash in Turkey.
"He's had tonsillitis," Ferguson told MUTV on Saturday. "We hope he'll be in tomorrow [for training] - we'll see what he's like then.
"If he does [come in], hopefully we can get him ready for Tuesday."
United have already progressed to the last 16 of the competition as group winners with four wins out of four.
