Spanish players fumed at the final whistle over the performance of Romanian official Vlad Iordachescu, with players having to be restrained from making physical contact with the referee.

Spain's rugby federation had shown pre-match concern over the appointment of Romania referee give the importance of the match but there complaints were ignored.

The two assistant referees were also Romanian.

World Rugby had no authority over the appointment of match officials for the match - that duty fell with Rugby Europe.

"We are in contact with Rugby Europe to understand the context of events relating to the Belgium v Spain match in Brussels on Sunday," a report reads.

Rugby Europe had released a statement on Sunday confirming the appointments were made before the Rugby Europe Championship, and confirmed during the tournament based on refs' performances.
