The France international winger has already been ruled out of the first leg later this month after he had surgery on a burst blood vessel in his bottom. He has been expected to return to action within the next two weeks, albeit with missing the first leg against Arsenal on 19th February certain. But according to German daily Bild, Ribery's comeback could be pushed further back, to such an extent it would mean him missing the second leg of the tie on 11th March.
