After being stretchered from the field, Evans underwent neck surgery at University Hospital Cardiff on Saturday night which Robson declared to be successful.

Robson said: “The surgery that Thom required - having sustained damage to his neck - went well.

"Thom had sustained slippage to one of the vertebrae and that required to be eased back into place. The surgeons are pleased with his progress, Thom has movement in his arms and legs and his family have been to visit him today, as have a number of his Glasgow Warriors team-mates.

"He will remain at the hospital today and if he continues to progress he will be allowed to travel back to Scotland into the care of the Glasgow Warriors medical team later this week.”

Paterson, who was winning his 100th cap for Scotland, was also forced to leave the field before halftime and is set to miss the rest of the Six Nations campaign.

Robson added: "Chris will also remain in hospital today after the damage he sustained to his right kidney. Fortunately he does not require surgery at present.

"In effect he has a massive bruise in the middle of his kidney but that will gradually repair itself and the medical team are also pleased with his progress."

Scotland boss Andy Robinson suffered a further blow when it was revealed Rory Lamont, only just back in the side after injury, suffered knee ligament damage during the 31-24 defeat.
