Dave Kilcoyne hoping to claim no.1 jersey from 'excellent' Cian Healy

There can be few more satisfying experiences for a replacement than coming off the bench and making an immediate impact and Ireland’s Dave Kilcoyne did just that last Sunday as he played his part in the hammering of the Scottish pack.

Ireland were already 19-3 up in Yokohama when Kilcoyne and fellow prop Andrew Porter were introduced in the 49th minute ahead of a green scrum. Moments later, the Scots were retreating and referee Wayne Barnes’s arm was aloft to signal an Irish penalty.
