Gordon D'Arcy and Keith Earls are both fitness doubts for Ireland's clash with England in the Six Nations on Sunday.
Leg and shoulder injuries could keep the duo out of the clash at the Aviva Stadium, whilst flanker Peter O'Mahony could play subject to International Rugby Board concussion guidelines.
"Gordon suffered a nasty dead leg but is recovering better than we expected," said Ireland team manager Mick Kearney.
"The prognosis is still guarded but we are more hopeful than we were yesterday. He will do modified training today and tomorrow.
"Keith took a blow to his left shoulder that was quite sore. The prognosis is guarded.
"He will do modified training today and tomorrow and will be reviewed by a specialist tomorrow.
"Peter took a bang to the head in a tackle and is being treated as concussion. He was fine after the game and was well today.
"He'll follow the IRB return to playing guidelines and it depends on how he recovers during the week."
Brian O'Driscoll, Rob Kearney and Mike Ross have all been passed fit, with Robbie Henshaw, Rhys Ruddock, Darren Cave and Andrew Trimble joining the squad as cover.
