An extraordinary schedule change happened: The Leverkusen - Köln match has been moved from Sunday the 7th of May to Friday, May the 5th, to give Leverkusen two more days to prepare for their Europa League match at Rome. Since the match originally scheduled on Friday between Mainz and Schalke can't be moved to Sunday for the reason of a big event happening at Mainz on that date (Gutenberg- Marathon), we'll have the unique case of two Friday and only 1 Sunday match on 31th matchday. Not amused they even considered moving the Mainz - Schalke match to Sunday, since Mainz and Gelsenkirchen are far away enough from each other to cause Schalke fans to take at least half a day off to make it possible to watch this match at the stadium. It would have been an insolence to move it to Sunday, with such short notice, for that reason.
