Friday's Bundesliga match between Eintracht Frankfurt and Karlsruhe has been postponed because of damage to the pitch caused by a Madonna concert.
The match was to have taken place at Frankfurt's Commerzbank-Arena stadium but the German Football League (DFL) said the grass had been too badly damaged by fans who watched the American pop diva in concert on Tuesday.
Stadium officials replaced part of the turf but there still remained too many irregularities, leaving it unplayable, it said.
After inspecting the pitch, DFL head Holger Hieronymus decided that the "physical safety of the players could not be assured".
The match between Frankfurt and Karlsruhe will be rescheduled at a later date.
