BERLIN — Paco Alcacer scored twice in injury time for Borussia Dortmund to reclaim the Bundesliga lead with a 2-0 win over Wolfsburg while Bayern Munich was held in Freiburg to 1-1 on Saturday.
Robert Lewandowski, who scored Bayern's equalizer after Freiburg shocked the visitors by taking a third-minute lead, missed a great injury-time chance and Leon Goretzka then struck the post for Bayern.
The end of Bayern's six-game winning run in the league allowed Dortmund to seize the lead by two points ahead of the sides' potentially league-deciding clash in Munich next weekend.
''We have to win to stay in the race, which is annoying because we had done so well to catch up,'' said Bayern coach Niko Kovac, whose side was trailing by nine points earlier in the season.
Dortmund went into what was sure to be a tough game without its best player, Marco Reus, who was excused so he could be with his partner for the birth of their first child.
Meanwhile, Bayern announced before its game that both goalkeeper Manuel Neuer, the captain, and defender David Alaba were ruled out with muscular problems.
Freiburg was without top scorer Nils Petersen due to a thigh problem, yet still managed to grab an early lead through Lucas Hoeler. The Freiburg forward also scored the equalizer in the sides' 1-1 draw on Nov. 3.
Lewandowski equalized acrobatically in the 22nd.
In contrast to Bayern, which had 27 efforts at goal, Dortmund created little going forward. Jadon Sancho finally tested Wolfsburg `keeper Koen Casteels for the first time after the hour-mark.
With defender Abdou Diallo going off injured early in the second half and his replacement, Achraf Hakimi, following him off some 20 minutes later, it was shaping up to be a frustrating afternoon for Dortmund.
Then Alcacer fired a free kick through the wall and Sancho set up the Spaniard for his second.
