Video: Edin Dzeko sent off for pantsing
Dzeko, a former Manchester City striker, was shown a second yellow card and was given his marching order in the 80th minute as he had already been booked in the first half.
Playing one man down, Bosnia eventually conceded Greece the equalizer with Tzavellas who levelled the game seconds before the final whistle.
Dzeko is Serie A’s top scorer having netted 10 goals in the opening 12 games of the season.
