Borussia Dortmund scored from the penalty spot and saw it overturned in absurd circumstances after a VAR review against Borussia Monchengladbach.
Edin Terzic's men were leading 2-1 at Borussia-Park as they attempted to get back to winning follow back-to-back defeats and keep pace with RB Leipzig in the race for Champions League football.
They had the chance to gain a two-goal lead minutes after the break when they were awarded a penalty as Jonas Omlin was deemed to have brought down Karim Adeyemi.
Marcel Sabitzer stepped up and converted but the referee blew the whistle almost immediately for a VAR review.
The penalty was eventually overturned as Omlin had won the ball fairly.
