De Luca to face Ireland
Nick De Luca comes into the Scotland side in the only change to head coach Andy Robinson's team for the RBS 6 Nations clash against Ireland in Dublin on Saturday.
De Luca replaces Rory Lamont, who suffered a broken leg during the defeat by France.
Sean Lamont will move outside to replace his brother on the wing with De Luca starting at centre.
Max Evans, who was cleared of an assault charge on Monday at Edinburgh Sheriff Court, is on the bench after recovering from an ankle injury.
Euan Murray, who missed the Sunday defeat by France for religious reasons, is also on the bench along with Ruaridh Jackson, who has recently overcome a hamstring injury.
Robinson said: "Ruaridh has worked hard and done well in his games with Glasgow. He had a tough time with injury following the Rugby World Cup but he has the strength of character required in international rugby.
"We are also delighted to see Max and Euan back in the squad and look forward to their contribution this weekend."
Ed Kalman and Duncan Weir drop off the bench after the 23-17 loss to France.
