Ireland's Six Nations preparations don't begin in earnest until tomorrow but Craig Casey has already earned high praise from captain Jonathan Sexton.

The young Munster scrum-half was a surprise inclusion in Andy Farrell's squad, edging out far more experienced nines in the other three provinces, and earning a return to the group to which he was attached as a development player during the Autumn Nations Cup.
