87 seconds in (although the author of the video would have you believe it's 93 and/or 83 seconds...nice editing buddy), Youseff Mohamad pulled down the onrushing attacker and unfortunately was the last defender. Straight red and no question about it.
It serves as the fastest red card ever issued in the German Bundesliga's 47 year history. Cologne went on to lose by a score of 3-1.
