Ireland will miss the services of second-row Iain Henderson for the remainder of the Six Nations tournament after he received a three-week ban for a red-card offence while playing for his club Ulster.
The 28-year-old was sent-off in the 76th minute during the second round of Pro14 game against Ospreys for a dangerous tackle.
As a result, he appeared before a Pro14 disciplinary panel and was initially handed a six-week ban that was reduced by half following his clean disciplinary record and other mitigating factors.
"A clean disciplinary record, co-operation throughout the process and remorse shown warranted mitigation of fifty percent, bringing his ban to three weeks," read the statement from Pro14.
Henderson will now miss Ireland's final two rounds of Six Nations games against Italy and France on 24th and 31st October respectively.
Ireland are positioned fourth in the Six Nations table with two wins from three games.
