The 24-year-old was injured in a collision at the Millennium Stadium and has remained in University Hospital Cardiff since his side’s bruising 31-24 loss.

There were serious concerns for Evans’ playing career when he was stretchered from the field and operation will be conducted by the same surgeons who operated on him originally.

But Scotland team doctor James Robson is delighted with the progress his charge is showing and is convinced he is making the right decision.

He said: “The surgeons are really pleased with the way everything is going and he has been heartened by the many messages of support he has received from around the world.

"He’s now decided to go ahead with the second procedure which should definitely help with the whole recovery process.”

Meanwhile Scotland’s other walking wounded are also taking tentative steps on the road to recovery.

Full-back Chris Paterson hopes to leave hospital in Cardiff on Wednesday after suffering kidney bruising while winger Rory Lamont is waiting on the results of a scan on his medial ligament.

Robson added: “They are in good spirits and Chris will be looking to get out of hospital very soon and travel back home with his wife in a few days.”
