The roof on the Principality Stadium will be closed for tonight’s crucial Six Nations meeting of Wales and Ireland. Both sides are unchanged after contrasting results in their last outings. Ireland beat France at the Aviva, and tonight’s hosts fell to Scotland at Murrayfield. With Wales having a point to prove, Ireland centre Robbie Henshaw knows the atmosphere will be raucous under the roof tonight. Starting openside tonight and former Wales captain Sam Warburton says they’re keen to avoid a third successive defeat.
