Tabaković, 31, will spend the 2025/26 campaign at Borussia-Park after struggling to break into the Hoffenheim team following his summer 2024 arrival.
The Switzerland-born Bosnia and Herzegovina international managed only three goals in 22 Bundesliga appearances, of which just six were starts as the Sinsheim club narrowly avoided relegation in 15th place. One of those goals came away at Gladbach in May’s 4-4 draw.
