Cian Healy’s suspension has been reduced by a week after an appeal in Glasgow today, with RTÉ rugby analyst George Hook branding the decision at outrage.
Healy argued that extending the three week suspension over four weekends was not permissible under current regulations.
The independent Six Nations Disciplinary Appeal Committee upheld the appeal and he is available for the final home match of the campaign against France.
Healy had been cited for an incident against England with prop Dan Cole which led to the ban.
Hook said the length of suspension does not reflect the seriousness of Healy's offence.
He tweeted: "Cian Healy gets an effective one-match suspension for trying to break a leg. An outrage; he should have been banned from the championship."
Healy's suspension will end at midnight on 3 March.
The forward missed Ireland's 12-8 defeat by Scotland at Murrayfield on Sunday which saw Declan Kidney’s side drop to fourth in the standings with one win from three games.
