Leinster happy with Sexton head test
Leinster are satisfied that they adhered to all the necessary protocols in their treatment of Johnny Sexton after the Ireland out-half, who has a lengthy history of multiple concussions, received another heavy blow in Friday night's Champions Cup clash with Montpellier.
"Well, we're happy that he passed it and was back on the field," said Leinster coach Stuart Lancaster. "If he hadn't passed it then he wouldn't have been back on the field. You've just got to trust the medical team.
"We're in the coaches' box, he gets taken off, we get the message that he's passed the HIA 1, 2 and 3 and as a consequence is back on the field. It is what it is."
Dr Barry O'Driscoll, who resigned as World Rugby medical chief over this issue, claimed weekend incidents confirmed the association "had lost control of concussion and what to do with it."
"Conor Murray and Johnny Sexton should have been off. Concussion was suspected in both, both have a history of suspected (concussion), both had brain injuries and both were put back on because they passed the protocols."
Former IRFU doctor Cliff Beirne added that he was "concerned about the HIA protocols".
Meanwhile, Sean Cronin's absence from the Six Nations has been confirmed after the Leinster hooker was ruled out of action for ten weeks with a hamstring injury.
