Six Nations: Gordon D'Arcy and Keith Earls doubful for Ireland's clash with England

D'Arcy suffered a dead-leg and Earls damaged his shoulder during Ireland's 30-22 victory over Wales on Saturday.

Team manager Mick Kearney said the Irish are "guarded" over the duo's chances of participating in the crucial clash, which follows England's victory over Scotland.

"Gordon suffered a nasty dead leg but is recovering better than we expected," Kearney said.

"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 O'Mahony was concussed at the Millennium Stadium but has improved rapidly and is in line to play, subject to International Rugby Board concussion guidelines.

"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," Kearney said.

"He'll follow the IRB return to playing guidelines and it depends on how he recovers during the week."

Brian O'Driscoll and Mike Ross played a full part in training on Tuesday after suffering a head wound and severe cramp, while Rob Kearney is available for Sunday despite his bruised back.

Connacht full-back Robbie Henshaw, Leinster back row Rhys Ruddock, Ulster centre Darren Cave and Ulster wing Andrew Trimble have been called up as cover.
