England head coach Eddie Jones insists the medical team followed protocols “to the absolute letter” with Elliot Daly against Scotland.
Daly had to come off early at Twickenham last Saturday after being met with a solid tackle from hooker Fraser Brown, who was yellow carded.
He passed the head injury assessment (HIA) and returned to the action, but complained of blurred vision and soon left the field permanently.
Jones has stood by his medical staff however, saying that Daly passed a second HIA after the game and that he could feature against Ireland.
“He had a test by the match doctor and was passed fit, went back on the field and had some blurred vision,” he told The Times.
“He was tested again by the match doctor at the end and passed fit.
“We don’t have any concerns at all that we followed the protocols to the absolute letter. He’s only got a busted nose now.
“He is following his protocol pretty closely. We are positive he is going to be okay. He is fine. Very well.”
