Ulster scrum-half John Cooney and uncapped Leinster fly-half Harry Byrne have joined the Irish camp to provide cover for injured duo Conor Murray and Johnny Sexton.

Captain Sexton came off against Wales for a head-injury assessment and will miss tomorrow's clash with France.

Scrum-half Murray also misses out as he is nursing a hamstring injury.

The half-back pairing are replaced this weekend by Jamison Gibson-Park and Billy Burns who start at nine and 10 while Craig Casey and Ross Byrne are in line to feature from the bench.
