A week after coach Mike Ruddock was pushed, captain Gareth Thomas is out of the remainder of Wales’ Six Nations campaign.
Thomas suffered a serious scare on Sunday night when he collapsed in front of the TV, causing him to fear for his life.
“Thomas has been ruled out of action for the remainder of the Six Nations after doctors examined results of an MRI scan this afternoon,” the WRU said in a statement.
“Gareth has sustained damage to an artery in his neck that caused the symptoms that he experienced on Sunday night and resulted in his admission to hospital,” it said.
“We expect him to make a full recovery and it is envisaged he will resume training in 10 to 12 weeks’ time.”
Thomas spoke of his ordeal to the Western Mail.
“I thought I was having a heart attack. I thought I was going to die.”
