Cardiff Blues number eight Robin Copeland and Scarlets full-back Liam Williams have been handed two-week bans at separate disciplinary hearings.
The pair appeared in Dublin on Thursday after being shown red in the RaboDirect PRO12 derby match on April 20 at the Millennium Stadium.
Copeland was sent off for a stamp to the head contrary to Law 10.4 (b) while Williams was cited for a dangerous tackle contrary to Law 10.4 (e).
"In the case of Williams, the player had been awarded a yellow card for the incident, his first of the match, which later resulted in a red card being issued for second of the two yellow cards he received. However the independent citing commissioner at the match cited Liam Williams for the dangerous tackle, in effect upgrading the yellow card to a red card," stated the PRO12.
"The independent disciplinary committee convened for the hearing, chaired by David Martin (Ireland), along with George Spotswood and Pat Barriscale (also Ireland), upheld the citing and imposed the sanction of a two-week suspension ending on midnight on Sunday 4th May 2014. The committee's view was that here was a heavy onus on the tackling player to ensure the safety of the player in the air.
"Both players have the right of appeal."
