Final score in Twickenham was England 23-22 Ireland.
Ireland head coach Andy Farrell says they'll learn lessons quickly from the 23-22 defeat to England in rugby union's Six Nations.
The holders saw hopes of back-to-back Grand Slams end at Twickenham - but can still retain the title on the final weekend.
Farrell says they're used to going again after a victory, so now must do the same following a loss:
