Wing Simon Zebo will miss the remainder for the championship with a broken foot, while fly-half Jonathan Sexton is a serious doubt for the next assignment against Scotland after tearing his hamstring. Centre Brian O'Driscoll, flanker Sean O'Brien, and locks Mike McCarthy and Donnacha Ryan also picked up knocks that will require close attention over the coming fortnight.
But Kidney is not giving up on the title yet, and said: "This gives England a bit of daylight with the other five sides on two points each with three matches to play. We're extremely disappointed because that wasn't the result we wanted. Let's see what France come up with at Twickenham. England have to go to Cardiff too."
He went on: "There's still a hell of a lot to play for. What we have now are three more opportunities to get three wins. Let's get to eight points and see where we are at the end of it.
"The Grand Slam is a wonderful thing to win, but first and foremost you play for the championship and we're still well in for that."

Time and again any Irish momentum was halted by unforced errors and even the wet conditions failed to account for the number of handling mistakes they made.
"I don't want to blame the conditions because both teams played in them," captain Jamie Heaslip said. "There were a lot of knock ons and unforced errors. I don't know what caused all the errors. It was frustrating and we constantly tried to regroup and go again. England played a good pressure game."
