Ireland prop Cian Healy has been slapped with a three-week suspension for stamping on Dan Cole during Sunday's defeat to England.
The 25-year-old loosehead was handed the ban at a disciplinary meeting in London on Wednesday and will now miss the Six Nations trip to Scotland on February 24 and the home game with France on March 9.
Healy trod on Cole's ankle during a maul, an incident which was missed by referee Jerome Garces.
The disciplinary committee ruled that the stamp be categorised as a mid-range offence in terms of seriousness, which carries a sanction of five weeks.
However, the committee allowed the maximum two weeks of mitigation, meaning his ban will end at midnight on 10 March.
Healy's suspension is a further blow to Ireland's hopes of getting their Six Nations campaign back on track, as they have a host of injury problems ahead of their visit to Murraryfield.
Simon Zebo has been ruled out of the remainder of the tournament with a broken metatarsal, while Jonathan Sexton is a major doubt for the Scotland game after injuring his hamstring in the 12-6 loss to England.
Head coach Declan Kidney also has concerns over former captain Brian O'Driscoll (ankle), Sean O'Brien (hamstring) and second rows Mike McCarthy (knee) and Donnacha Ryan (back).
Declan Kilcoyne is likely replace Healy at loosehead while there could be a recall for Ulster's Tom Court.
