Croatia are facing the prospect of UEFA sanctions after several flares were thrown on to the pitch and fighting broke out in the stands late on in their Euro 2016 draw with the Czech Republic on Friday.
One steward was nearly hit by a firecracker which also just missed Croatia goalscorer Ivan Perisic. After receiving immediate attention it was established that the steward did not need hospital treatment.
However, Press Association Sport understands a disciplinary case against the Croatian Football Federation is set to be opened on Saturday.
Croatia are already facing action over disturbances during their Group D opener against Turkey last Saturday - and they were also docked a point in their qualifying campaign after a swastika symbol was seen on their pitch.
Former Croatia manager Slaven Bilic warned there will be more crowd trouble after condemning the violent scenes which marred Friday's 2-2 draw.
The West Ham boss, who managed his country between 2006 and 2012, helping them to third place in the 1998 World Cup in France, told ITV he expects to see more problems.
The Czechs equalised with a penalty in time added on after the disturbances and Bilic said: ''It's unbelievable what those people are doing.
"The majority of the fans are telling them to not do it. Some of them are there on a mission. It's probably not the last time they'll do it.
''Back home it's not the greatest league but it's competitive. When there's a big derby between (Dinamo) Zagreb and (Hajduk) Split people are not taking their kids because they know it'll be dangerous.''
It is understood that some fans, in a dispute with their FA, might be deliberately causing trouble in order to prompt disciplinary action against the governing body.
Bilic briefly outlined the issue fans have against the Croatian Football Association.
He said: ''Croatia rarely play in Split, in my hometown, and they think it's all about Zagreb. It's between the north and the south, Zagreb and Split - the two biggest clubs.
"Now Zagreb is becoming the biggest club in the Balkan area while Split has no money, no everything. That's the issue without going into the details.''
Croatia blew a 2-0 lead in the last 15 minutes as they were denied the chance to qualify for the second round.
Perisic and Ivan Rakitic put them in control only for Milan Skoda and Tomas Necid's stoppage-time penalty, after Domagoj Vida's handball, to rescue the Czech Republic.
