Wales winger George North could be a doubt for the Six Nations championship after being carried off on a stretcher with head and neck injuries in Scarlets's 47-17 defeat at Ulster on Friday.
Scarlets backs coach Mark Jones told the BBC: “I only know what I saw on the replay. He's had a knee to the head and he's struggling with some head and neck issues.”
Six Nations grand slam champions Wales, who have lost seven games in a row since their triumph in March, begin the defence of their title on Feb. 2 at home to Ireland.
Wales have been hit by a string of injury problems in recent months with flyhalf Rhys Priestland already out of the Six Nations with a ruptured Achilles tendon. – Reuters
