Bundesliga high-flyers Eintracht Frankfurt and Freiburg could not be separated on Friday, playing out a 0-0 draw at Mage Solar Stadion.
Visitors Frankfurt looked to have opened the scoring as early as the 12th minute through Stefan Aigner, only for the goal to be ruled out for offside.
Aigner found himself in the spotlight again early in the contest, heading wide from a good position before missing the target again on 16 minutes.
It took the hosts until close to the hour mark to threaten the Frankfurt goal, Jan Rosenthal and then Matthias Ginter forcing Stefano Celozzi to clear off the line in quick succession.
With 14 minutes remaining, Jonathan Schmid was played through on goal by Max Kruse, but Frankfurt goalkeeper Kevin Trapp pulled off a good stop to preserve the deadlock.
Johannes Flum then missed a chance to win the game for the home side with in the 85th minute, heading over the bar from Rosenthal's inviting delivery.
The draw sees Frankfurt stay fourth, three points ahead of Freiburg, who have defied expectations so far this season to sit fifth in the standings.
