Cardiff Blues Director of Coaching David Young said: "Xavier is back in training and should be pushing for some involvement in the Leinster game.
"Then hopefully he will be ready for selection for the Heineken Cup games. We've done well without him but there is no doubt he will give the squad a massive lift."
