Ireland centres Brian O'Driscoll and Gordon D'Arcy have been included in a preliminary 33-strong squad for the RBS 6 Nations clash with England on Sunday week.
The Leinster duo sat out Saturday's 40-13 victory over Scotland after sustaining hamstring injuries during Ireland's championship opener against Italy.
Both players featured in the initial line-up for the trip to Murrayfield but were withdrawn from the side when they failed to recover in time.
Their rehabilitation has continued this week at a specialist cryotherapy centre in Spala, Poland, and their injuries will be assessed once again on Sunday.
Ireland coach Eddie O'Sullivan has added nine other players to the 22 used against Scotland as his side prepare for the next match in their Grand Slam bid.
O'Sullivan will name his side to face England on Wednesday, with lock Paul O'Connell retaining the leadership duties should O'Driscoll remain in the treatment room.
