Udinese’s UEFA Cup fixture with Dinamo Zagreb in December was temporarily suspended due to the away support throwing lit flares onto the field of play.
The act occurred deep into the match, leaving Israeli referee Alan Yefet little choice but to stop play for five minutes in order for the smoke to clear from the pitch.
Members of the Zagreb team appealed to their fans in an attempt to calm them down so that the match could reach a conclusion.
Off-field events overshadowed the on-pitch affairs - Udinese won by two goals to one - and one Zagreb fan even fell from the stand and had to receive hospital treatment for head injuries and a broken nose.
After the match 12 Croatians were stopped by police under suspicion of vandalising property.
In reaction to this, UEFA have decided that Dinamo's next home match in European competition will be staged behind-closed-doors, with a further game deferred for a probationary period.
Dinamo were also fined a total of €150,000, with €50,000 deferred for a probationary three-year period.
