Ireland will be without the services of star prop Andrew Porter for their final two fixtures of this year's Six Nations against England and Scotland.
In a substantial blow to Andy Farrell's side ahead of their trip to Twickenham on March 12, Irish Rugby confirmed a scan of Porter's ankle revealed he would miss the tournament run-in.
The 26-year-old has returned to provincial employers Leinster to receive treatment for the injury, which he appeared to suffer early in the second half of Sunday's 57-6 win over Italy.
