Borussia Dortmund missed a chance to climb past RB Leipzig into second, conceding an equaliser in a 1-1 draw at Freiburg after Jobe Bellingham saw red.
Ramy Bensebaini's 31st-minute goal had Dortmund in front but Bellingham was sent off for a professional foul shortly after half-time.
The hosts made the most of their one-man advantage, camping out in Dortmund's half and levelling things up thanks to an acrobatic Lucas Holer strike.
"We're definitely disappointed," Dortmund's Gregor Kobel told DAZN.
"If the red card doesn't happen, the result would look different. We had the game under control and were very dominant."
Dortmund striker Serhou Guirassy missed a header while unmarked in the box five minutes in, continuing his recent dry spell.
Guirassy scored 38 goals in all competitions last season but has just one in his past 10 Bundesliga matches.
The visitors had looked comfortable after Bensebaini's goal but lost control of the match when Bellingham, as the last man, felled an on-rushing Philipp Treu on the edge of the box.
With Freiburg peppering the Dortmund goal, Kobel made a string of impressive saves but could not keep out Holer's curling strike.
