Spahic could be punished by the Germany Football Federation (DFB) "for the flagrant anti-sporting gesture" based on photos taken during during the 1-1 draw.

The DFB confirmed that Spahic, 33, will appear before a disciplinary commission and that probes have also been opened into the behaviour of coaches Gertjan Verbeek (Nuremberg) and Thorsten Lieberknecht (Braunschweig).

Verbeek blasted the referee as biased following his side's 3-2 loss to Freiburg (3-2), while Lieberknecht was sent to the stands by the referee in his side's match against Leverkusen, his third sending off this season.
