Munster’s charge towards the top four of the Pro12 hit a speed bump as they slipped to a 37-28 defeat at Cardiff Blues.

Robin Copeland’s return to the BT Cardiff Arms Park where he enjoyed two highly successful years before linking up with Munster this season and the first appearance of Argentine international Luis Gonzalez Amorosino on the wing for Cardiff Blues adds considerable interest to this evening’s Guinness Pro12 clash.
