Afoa, the New Zealand World Cup winner, will appear before independent judicial officer Jean-Noel Couraud in Dublin on Thursday following his challenge on Munster full-back Felix Jones after 46 minutes of Ulster's 22-16 victory at Thomond Park.

If Afoa is found guilty, International Rugby Board guidelines state the minimum entry level suspension for a dangerous tackle is three weeks.

Ulster's semi-final showdown with Edinburgh is at the Aviva Stadium on April 28.
