Ross Ford, Jonny Gray and Sean O'Brien have all been banned resulting in them missing their country's World Cup Quarter Finals clashes.
Irish Back Row, Sean O'Brien, has been banned for one week following his punch on French Second Row Pascal Pape. The punch was spotted initially by pundit and former England Back Row Lawrence Dallaglio.
Pape went down injured after the strike and needed medical attention, but he recovered to continue playing in the match. The incident went unnoticed by the Referee but was caught by the citing officer and has led to O'Brien's ban.

Due to the ban, he will miss Ireland's Quarter Final clash with Argentina leaving Ireland woefully short on Back Rows after Peter O'Mahony was ruled out of the World Cup with knee ligament damage.
Ireland have 48 hours to appeal the ban.
Elsewhere Paul O'Connell's international career has been ended due to a Hamstring tear that left him in obvious discomfort on the pitch confirming that would be his last appearance for the Irish.
Scotland suffered a huge blow with both Second Row Jonny Gray and Hooker Ross Ford receiving three-week bans for their dangerous tackle on Samoan Back Row Jack Lam.
The ban seems harsh, especially on Ford as he seemed to be unaware of Gray having started the tackle and Lam suffering no obvious injury.
The bans are a huge setback to Scotland's hopes to defeat Australia with both players having started three games throughout the tournament so far.
The bans have ruled out the two players for the remainder of the tournament but Scotland have 48 hours to appeal and it seems there is no doubt that they will do so.
