Courtney Lawes’ participation in the Guinness Six Nations is under threat after he was ruled of Saturday’s pivotal clash with Wales by a chest problem.

Lawes will miss the Cardiff showdown, described by Eddie Jones as “make or break” for both sides, after injuring his pectoral muscle during Wednesday’s full-blooded training session.
