Alex Goode and Jack Nowell come into the England team to face Ireland as Stuart Lancaster makes two changes to his team for Sunday.
With Mike Brown having failed to recover from the head injury he suffered against Italy, Goode comes in at full-back as a straight swap, while Nowell replaces Jonny May, dropped after a disappointing display against the Azzurri.
Elsewhere Lancaster has stuck with the same side that won the first two games of the competition, with the only other change coming on the bench where Henry Thomas replaces Kieran Brookes as tighthead cover.
England have won all three games against Ireland under Lancaster, but travel to Dublin to face an Irish side chasing a record-equalling tenth win this weekend.
"We’ve made minimal changes as we felt the squad have performed well in the first two games," Lancaster said.
"Alex is in good form for Saracens and has been training well over the last few weeks, as has Jack, who is also playing well for Exeter.
"Both have been pushing hard for selection and I am sure will seize their chance against a high quality Ireland side.
"Chris Pennell and Manu Tuilagi will also travel. Manu has been recovering with us and so it’s good to continue keeping him connected."
