George North: Luther Burrell backs head injury decision

England's Luther Burrell says Wales' George North "seemed fine" at the end of Friday's Six Nations opener, despite taking two heavy hits to the head.

North remained on the field following a second blow to the head in the 21-16 loss to England, prompting an investigation into how the injuries were handled by World Rugby.

Jamie Roberts, a qualified doctor, has also insisted that players fully trust their medical teams.
