Ireland launched their bid for a third consecutive Six Nations title with a hard-fought 27-22 bonus-point victory over England in Dublin, overcoming a sluggish first half with a dominant second-half performance.
England started strongly, with debutant Cadan Murley scoring early and the visitors leading at halftime after a well-executed defensive display.
However, Ireland roared back after the break, with tries from Bundee Aki, Tadhg Beirne, and returning hooker Dan Sheehan sealing the win under interim head coach Simon Easterby.
Despite late consolation tries from Tom Curry and Tommy Freeman, England suffered their sixth defeat in seven games under Steve Borthwick, while Ireland took a crucial first step toward another championship, setting up an exciting clash against Scotland next week.
