Werder Bremen suffered their first defeat under coach Ole Werner and lost their lead in the 2nd Bundesliga.
The Bundesliga relegated lost in the eleventh game under the new coach 1: 2 (0: 1) at 1. FC Heidenheim and had to let the equal points competitors Darmstadt 98 and FC St. Pauli pass.
Christian Kühlwetter (38') gave the hosts the lead with a long-range shot into the top corner, ending their run of four games without a win and improving to fifth place.
Stefan Schimmer (63rd) sealed the first Bremen bankruptcy since November 27, 2021 (1: 2 at Holstein Kiel).
Shortly before the end, Heidenheim's Marnon Busch saw the red card (87', according to video evidence), and Marvin Ducksch (89') ensured a thrilling final minute with a direct free kick.
In a varied and entertaining game, Heidenheim got off to a better start in front of 11,250 spectators.
But Werder worked their way into the game and created a few good chances, which, however, were destroyed by the strong goalkeeper Kevin Müller.
After the change of sides, Bremen continued to increase their attacking efforts.
On the other side, keeper Jiri Pavlenka prevented the 0:2 (61st) from a counterattack by the hosts with a brilliant save against Schimmer.
Just two minutes later, Werder defender Anthony Jung failed with a bad pass in his own penalty area and this time Schimmer scored.
