Just before the start of the match, three flares fell onto the field, one in the midfield, another in the stands, and the third one right in the same bench.
Beforehand, the fans of Hannover and Wolfsburg were already confronting each other and this reached the field of play.
Fortunately, the incident did not go beyond a bad anecdote in the Bundesliga. The players sitting on the bench stood up immediately and escaped from the flare.
