Connacht backs coach Nigel Carolan says another “ruthless” performance is necessary to have any chance against Edinburgh in tonight’s Guinness PRO14 clash (7.35pm, eir Sport).

Ireland U20 out-half Ben Healy will make his Munster senior debut tomorrow night as Johann van Graan opts for wholesale changes for the PRO14 visit of Edinburgh to Cork.

Connacht have given themselves a good chance of reaching the knockout stages of the Challenge Cup for the 11th time after securing a bonus point win at Stade Aime Giral.
