The rushing of the fans at 1. FC Köln and FC Schalke 04 will most likely have consequences for both clubs.
The control committee of the German Football Association has started investigations after the incidents on Saturday in the 1st and 2nd Bundesliga, as a DFB spokesman confirmed. The clubs were asked to comment.
In Cologne, numerous spectators ran onto the pitch after the final whistle to celebrate their team.
Around 2,000 fans stormed the pitch when Schalke rose to the Bundesliga and, in initial euphoria, secured pieces of the grass and the goal nets for themselves.
