VfB Stuttgart squandered the chance to lift themselves further away from trouble when they conceded a late penalty to draw 1-1 at Mainz on Sunday.
Former Germany keeper Jens Lehmann was sent off three minutes from time after blocking the ball and pushing Mainz striker Aristide Bance for no apparent reason, the referee awarding a penalty which was converted by Eugen Polanski.
Stuttgart's Pavel Pogrebnyak had used his knee to direct an Arthur Boka cross into the net from five metres on 11 minutes to give Stuttgart the lead. Stuttgart, who have qualified for the Champions League knockout stage, are in 15th place on 13 points.
Bayer Leverkusen top the standings on 32 points, with Schalke 04 in second place, a point behind. On a snowy and bitterly cold afternoon, Stuttgart looked to be cruising to their first league win since late September and only their third this season when Pogrebnayk grabbed the early lead.
New coach Christian Gross who took over last week and saw his team qualify in the Champions League in his first match in charge, looked content as Stuttgart dominated and missed a chance to double their lead through Ciprian Marica.
Mainz battled on and came close in the second half when Florian Heller whipped in a low cross from the right but none of the Mainz strikers could connect at the goalmouth.
With three minutes left the match was turned on its head, with the notoriously temperamental Lehmann, fined in midweek by his club for comments in the press regarding Stuttgart fans, pushing the Burkina Faso striker after blocking the ball
"He steps on (Bance's) foot," said Stuttgart sporting director Horst Heldt. "He played great throughout the match and it is extremely bitter that this happened. We now have to live with it."
Polanski sent substitute keeper Sven Ulreich the wrong way to grab a point for Mainz, who moved up to eighth place on 24 points.
Lucas Barrios scored two early goals to help Borussia Dortmund to a comfortable victory at Wolfsburg and extend their unbeaten streak to nine games.
Barrios scored in the eighth and 10th minutes to give the visitors a 2-0 lead. Patrick Owomoyela made it 3-0 after 37 minutes with Grafite pulling one back 10 minutes into the second half.
Jurgen Klopp's Dortmund have collected six wins and three draws in the last nine games to jump to sixth place in the Bundesliga. Defending champions Wolfsburg have not won in their last four games to remain on 23 points and drop to ninth place.
