European football's ruling body UEFA has opened disciplinary proceedings into Romanian club Unirea Urziceni following the violence-marred Champions League match with visitors Rangers on Wednesday.

UEFA said Friday it would be looking into the club's "lack of organisation" during the match, which ended 1-1 in Bucharest after scuffles broke out between Rangers fans and security officials.

It was reported that some visiting fans arrived late in the stadium and were shepherded to a section already decked out with banners from home fans, leading to scuffles and police intervening with tear gas.
