Rangers have already been charged over the improper conduct of their supporters during the 1-1 draw in Bucharest.

But the Romanians are now also under investigation over a "lack of organisation" regarding the entry procedure for spectators.

The governing body's control and disciplinary body will deal with both cases next Thursday, November 12.

Meanwhile, Dinamo Zagreb have lodged a formal appeal against their three-point Europa League deduction following crowd trouble at their game with Timisoara on October 1. No date has yet been confirmed for the appeal hearing.
