Scotland have called up thirteen additional players ahead of their Six Nations Championship match against Ireland at Murrayfield on Sunday.

The only absentee from the 23 on duty in the victory against Italy nine days ago is Euan Murray who is unavailable for round three for reasons of his Christian faith.

The players called up are forwards: Jon Welsh, Dougie Hall, Tom Ryder, John Barclay (all Glasgow Warriors), Alasdair Dickinson and Richie Vernon (Sale Sharks) and Grant Gilchrist (Edinburgh Rugby), backs: Sean Kennedy, Alex Dunbar, Peter Horne, Peter Murchie (all Glasgow Warriors), Tom Heathcote (Bath Rugby) and Nikki Walker (Worcester Warriors).

The Scotland team to play Ireland is due to be announced on Wednesday.
