McGrath and Marmion can fill Murray void - Sexton

Ireland fly-half Johnny Sexton says Kieran Marmion, Luke McGrath and John Cooney are good enough to replace injured scrum-half Conor Murray against the All Blacks.

Murray won't feature against New Zealand after a neck injury sidelined the Munster man during Ireland's summer tour of Australia.

Sexton also believes Ireland are up to the task of beating the top ranked side in the world.
