The Bundesliga 2 club announced the news in the wake of Tuesday evening's 1-0 defeat against VfR Aalen.
Drawing the line
Schubert, 41, arrived at the club from SC Paderborn 07 in the summer of 2011, signing a contract lasting until 30 June 2013. However, after just one win from seven outings this term, the promotion hopefuls decided a change was in order.
"Recent sporting developments made this a necessary measure," explained club president Stefan Orth. "The match against Aalen was a low point. The things we discussed with Andre Schubert to improve the side in may haven't had the desired effect. There have been no signs of improvement and the situation has become serious, so we had to act."
Trio in temporary charge
Schubert's former assistants Thomas Meggle and Timo Schultz will take over first-team affairs, supported by goalkeeping coach Mathias Hain, for the upcoming matches against Jahn Regensburg and Union Berlin.
