Ireland’s preparations for this summer’s Nations Championship Southern Series take a major hit as both Caelan Doris and Tommy O’Brien are ruled out due to injury. RTE News reports that the absence of the pair is confirmed, leaving Ireland to adjust its squads ahead of the upcoming games. Sky Sports similarly states that Ireland captain Caelan Doris is ruled out of the Nations Championship Southern Series and that Tommy O’Brien is also unavailable. The two outlets agree that the injuries prevent both players from taking part in the tournament matches. While details of the specific injuries are not provided in the excerpts, the decision confirms they will miss the competition entirely. The withdrawals are expected to impact team selection and depth in Ireland’s campaign for the Nations Championship during the summer period, with replacements likely to be named as Ireland progresses through preparations.
