Cian Healy will miss Leinster's festive Pro14 inter-provincial derbies after being banned for three matches over an incident against Exeter Chiefs.
Healy was reprimanded for the use of his forearm during the European Champions Cup win on Saturday.
He received a yellow card but a disciplinary panel found that it warranted a red card.
A minimum two-week ban was imposed plus an additional seven days for his poor previous disciplinary record. Healy will miss the Boxing Day meeting with Munster, a New Year's Day encounter against Connacht.
