John Afoa could miss Ulster's Heineken Cup semi-final after being cited for a dangerous tackle on Munster fullback Felix Jones.
The New Zealand prop could be banned for as long as 10 weeks for the tackle, which occurred 46 minutes into his side's 22-16 win at Thomond Park.
Afoa will stand before independent judicial officer Jean-Noel Couraud in Dublin on Thursday.
If found guilty, the 28-year-old may have to sit out of his team's clash with Edinburgh at the Aviva Stadium on April 28.
