Exeter's Jack Nowell is in line to start on the wing for England in Sunday's Six Nations match with Ireland in Dublin.
Nowell has replaced Gloucester's Jonny May in a 26-man training squad.
May, who started the 47-17 win over Italy, has been sent back to play for his club side.
Full-backs Alex Goode and Chris Pennell stay in the squad as cover for Mike Brown, who has suffered a setback in his recovery from concussion.
Brown, 29, was stretchered off in the first half of England's 47-17 win over Italy at Twickenham on 14 February.
Bath tighthead prop Henry Thomas will join the squad on Wednesday as injury cover for Kieran Brookes.
Nowell has failed to make the squad for either of England's first two matches, both wins, having played every game on the wing in last season's tournament.
However, he inspired Exeter to a 32-21 victory over Harlequins on Saturday, prompting Chiefs head coach Rob Baxter to say it would be "very difficult" for England to overlook him.
England head coach Stuart Lancaster said: "Preparation has gone well and we've had a good build up so far.
"The guys who played against Wales and Italy did really well and the good thing is that others who are now fit and training are pushing hard for selection.
"We've had to make some tough decisions but it's a good position to be in and those players going back to their clubs have another big weekend ahead to lay down a marker for later in the tournament."
