Romania flanker Valentin Ursache will not be available for selection when his country plays against Ireland in a Pool D fixture at the Wembley Stadium on Sunday.
Ursache, who was cited for a dangerous tackle during the 38-11 defeat against France last week, has since been hit with a one-week ban. His offence was deemed to have been minor, despite being worthy of citing.
Also taken into account was his previous disciplinary record and the absence of any aggravating factors. What would have been a two-week suspension was then cut to one.
The Romanian will not be able to compete in any matches that take place before September 28, but has been granted 48 hours to appeal his suspension.
