Ireland coach Declan Kidney has named an unchanged line-up for Sunday's Six Nations clash with England in Dublin.
Flanker Peter O'Mahony, who suffered a head knock, and backs Gordon D'Arcy (dead leg) and Keith Earls (shoulder) were all passed fit after suffering injuries during Ireland's tournament-opening 30-22 win over Grand Slam champions Wales in Cardiff last weekend.
Sunday's match is already being billed as a potential title-decider after England defeated Scotland 38-18 at Twickenham in the first round.
"The players have recovered pretty well from the Wales game. We took 48 hours off after the match and have toned down training since," said Kidney.
"Gordon, Peter and Sean all trained fully this morning so we don't envisage there being any changes."
"We're not getting carried away with the performance against Wales," said Heaslip.
"If anyone did they were brought crashing down when they watched the video of the game. We were quite clinical in the first half but we made a lot of mistakes in the second half."
Ireland: 15 Rob Kearney, 14 Craig Gilroy, 13 Brian O'Driscoll, 12 Gordon D'Arcy, 11 Simon Zebo, 10 Jonathan Sexton, 9 Conor Murray, 8 Jamie Heaslip (c), 7 Sean O'Brien, 6 Peter O'Mahony, 5 Donnacha Ryan, 4 Mike McCarthy , 3 Mike Ross, 2 Rory Best, 1 Cian Healy.
