Leinster have confirmed winger Luke Fitzgerald is likely to miss the rest of the season after he ruptured his anterior cruciate ligament in Ireland’s 22-15 defeat to Italy in the Stadio Olimpico on Saturday.

Jordan Coghlan suffered an ankle injury in last week's 'A' interprovincial friendly against Munster is likely to be out for a number of weeks.
