Struggling Hertha Berlin conceded a goal with just seconds remaining to draw 1-1 with Mainz and deny themselves a much-needed win in the Bundesliga.
Lucas Tousart's header broke the deadlock for the visitors in the 30th minute when Maxim Leitsch's attempt to clear the ball found Chidera Ejuke, who lifted the ball to Tousart.
After the break, Mainz complained of a possible red card for Hertha captain Marvin Plattenhardt and also a penalty situation, but both requests were ruled out by the referee.
The hosts had a better spell in the second half and pressed Hertha during the final minutes. The hard fight paid off and Anthony Caci volleyed home the equaliser on added time.
Both sides, however, left the pitch unhappy.
Mainz sporting director Martin Schmidt said his team did "far too little for a long time.
"We had problems with the aggressiveness of the opponent."
On Hertha's side, Plattenhardt said the final result was "very bitter."
"Unfortunately, we couldn't avoid the goal. That's definitely two points lost," he told broadcasters DAZN.
Hertha are now 12th, one point above the relegation play-off spot occupied by VfL Wolfsburg, who travel to leaders Union Berlin on Sunday.
Mainz remain sixth with 11 points, but can drop out of the Conference League spot depending on the results at the weekend.
Saturday's games include champions Bayern Munich at Augsburg and the Ruhr derby between Borussia Dortmund and Schalke.
