Scotland wing Thom Evans has undergone surgery on his neck after suffering an injury during his country's 31-24 Six Nations defeat by Wales here on Saturday.

The 24-year-old was taken off on a stretcher, after several minutes of on-field treatment, shortly before half-time at the Millennium Stadium following a collision with Wales full-back Lee Byrne, where the wing also appeared to be hit from behind by other covering Welsh players.

"Thom has sustained damage to his neck that has required surgery," team doctor James Robson told Scottish Rugby's official website.

"He is moving his arms and legs and we are hoping for a speedy recovery.

"There will be a further bulletin in due course."

Scotland coach Andy Robinson had earlier described the injury as "very serious" and revealed that the player's parents had rushed to hospital to be with him.

Full-back Chris Paterson was taken off injured while making his 100th international appearance and he was also due to spend the night in hospital.

"Chris sustained damage to his right kidney during a collision in the first half," said Robson.

"On admission to hospital, it became evident that the damage would require a period of observation and, in particular, bed rest in order to aid his recuperation."

Evans's brother Max came off the bench to score Scotland's second try as they built an 18-9 interval advantage.

Wales, however, came from 10 points behind with four minutes to play as tries from wings Leigh Halfpenny and Shane Williams helped clinch a dramatic win in a match where Scotland had two players sin-binned in the frantic closing stages.

Scotland continue their Six Nations campaign away to Italy in Rome on February 27.
