On 1 September 2013, Ibišević netted a hat-trick against former club Hoffenheim, powering his side to a 6–2 victory at the Mercedes-Benz Arena. He was given a five-match ban on 9 February for appearing to strike Jan-Ingwer Callsen-Bracker in a home defeat to FC Augsburg. The German Football Association's decision was reached as Ibišević was labelled as a "repeat offender", having been sent off for a similar offence at the start of the previous season. The suspension would cause him to miss a game against his former team, 1899 Hoffenheim, and bottom team Eintracht Braunschweig. Ibišević apologised for his actions.
