A replacement for the Ulster hooker, who has been playing the best rugby of his Ireland career, has yet to be summoned and a clearer picture over his condition will emerge tomorrow.

“Rory’s doubtful for the weekend but we haven’t written him off just yet,” said manager Paul McNaughton.

“We’ll assess it tomorrow and have more information then. He’s definitely doubtful.

“He’s getting manipulation at the moment. We’ll have a better idea tomorrow after a morning’s treatment.”

Connacht hooker Sean Cronin deputised for Best against Italy and looks set to start the crunch game with Wales. Damian Varley, who flew out to New Zealand as cover for Flannery, should earn a call-up to the bench as cover.
