Iain Henderson could miss Six Nations

Iain Henderson should discover later whether suspension will end his Six Nations efforts before they begun.
The Ulster lock is to appear before a Pro 14 disciplinary panel after being cited for an alleged neck-roll challenge on Ospreys flanker Sam Cross.
Henderson only made his comeback from a thumb injury in Friday's game in Bridgend, after missing Ireland's opening two Six Nations games with England and Scotland.
Meanwhile he Ireland squad will train fully at Carton House today ahead of Sunday's Six Nations trip to Italy.
Tadhg Beirne is back in contention after re-joining the panel yesterday.
While it's hoped his Munster team-mate Chris Farrell's knee injury won't rule him out of the trip to Rome.
