Commenting on his squad selection, Matt Williams said: "It's been a tough week with so many guys returning to training from international duty, but it's great to be able to include the likes of Rory Best and Paddy Wallace in the squad. With the squad selection we've given some more players the opportunity to perform."
Roger Wilson is included in the squad for the first time since breaking his thumb at the end of November. The Ireland-capped back rower will be pleased to get the nod as his return to rugby was further hampered recently when he strained his right hamstring in training.
Also returning to the squad is Australian-born prop Tom Court. He has been drafted in for Declan Fitzpatrick who sustained an injury during the Ireland 'A' side's heavy defeat to their Scottish counterparts.
