By Padraic Halpin DUBLIN (Reuters) -Ireland had to come from behind against England to get their bid for a third successive Six Nations title off to a winning 27-22 bonus point start on Saturday thanks to a ferocious second half after the visitors had made life very uncomfortable for a time.

Ireland got off to a five-point start to its bid for an unprecedented third straight outright Six Nations rugby title, overpowering England in a second-half recovery to rack up a 27-22 victory in Dublin on Saturday.

Ireland win a five metre scrum in the strangest of circumstances. Try scorer Cadan Murley misjudges the high ball, touches it and then forced to try play it out of the try zone. Ireland pile on the pressure and force England back to win the scrum. A bad mistake from the debut boy.
