Wallace World Cup woe for Ireland
Ireland flanker David Wallace has been ruled out of the World Cup after sustaining a knee injury in Saturday's 20-9 defeat by England at Aviva Stadium.
Wallace was driven from the pitch by a medical cart in the 21st minute after twisting his right knee while being tackled by Manu Tuilagi.
"David took a very bad bang on the knee and while we don't know the exact prognosis, he has unfortunately been ruled out of the World Cup," said Ireland coach Declan Kidney.
Kidney, who will name Wallace's replacement on Sunday, admitted the Lions openside's withdrawal was "heartbreaking" for Ireland and the player.
"David took the news like the man he is. There's a word I'm not supposed to say in public, but it happens," he said.
"You have to deal with these things. He's 35 and I've never seen a man as physically fit as he is right now. Never.
"It's heartbreaking for him and his family. It's extremely disappointing for us and will be good news for someone else. That's the cut-throat nature of sport."
A highly attritional match saw Ireland finish with a number of injury concerns - Cian Healy (eye), Jerry Flannery (shin), Stephen Ferris (hand) and Jamie Heaslip (concussion) - although apart from Wallace all are expected to be available to face the USA on September 11.
Kidney eased concerns over Heaslip's condition, saying: "Jamie had to come off, but has come around fine and is talking away to the lads.
"Hopefully with a bit of a rest he'll be OK."
