The news today that Ronan O'Gara's long and distinguished playing time is over, brings to a close what was by any standards, a remarkable career.
The teams have met previously in the pool stages which saw the Six Nations Champions England narrowly defeat the Irish side 20-15.
Both sides will be vying for 5th spot in the championship with Australia and France also in contention.
The Ireland v England fixture will be shown live on Sky Sports and TG4.
