Ireland remain on course to retain their Six Nations title, and possibly even the Grand Slam. 

They've beaten England 19-9 at the Aviva Stadium, and with it, inflict a first defeat of the championship on the Red Rose. 

Robbie Henshaw got the game's only try, while Johnny Sexton kicked four penalties from five attempts before withdrawing with what looked like a hamstring strain. 

Sean O'Brien, however, suffered a bad blow in the first half, and had to be replaced.
