Ireland coach Eddie O'Sullivan has called Munster centre Barry Murphy into his RBS 6 Nations training squad as cover for calf injury victim Girvan Dempsey.
The 23-year-old Murphy scored a scintillating try and was voted man of the match in Munster's 31-9 Heineken Cup pool win against Sale on Saturday.
Full-back Dempsey, who has been in sensational form for Leinster this season, took a knock to his calf in his province's Heineken Cup win over Bath, and was not available for training with the Irish squad today.
The injury will be assessed by the Ireland medical staff over the coming days.
O'Sullivan's 35-man squad for the forthcoming RBS 6 Nations championship assembled at a south Dublin hotel last night after their Heineken Cup exertions.
In addition to Dempsey's injury, a total of 17 players were unavailable for training today due to various minor injuries, forcing O'Sullivan to cancel this afternoon's planned session.
O'Sullivan said: "Although none of the injuries are a major fitness concern, given the fatigue levels after the weekend, there is no benefit to be had from training today.
"The players will need some time to recover from what was a tough but hugely successful weekend for Ireland in Europe. The extra day's rest will allow the players to recover sufficiently to hit the ground running tomorrow.
Commenting on the inclusion of youngster Murphy, O'Sullivan added: Barry has shown significant improvement with every game he has played this year with Munster. His call up to the national squad is due reward for his performances to date.
Murphy has played in all six of Munster's Heineken Cup games this season, starting three games against Sale twice and Castres.
A former Ireland Under-21 international, he made his Munster debut against the Dragons in the Celtic League in 2003.
Ireland open their RBS 6 Nations account against Italy at Lansdowne Road on February 4.
