Holstein Kiel 3-0 Eintracht Braunschweig
Goals: 1-0 Skrzybski (12'), 2-0 Skrzybski (73'), 3-0 Pichler (82')

Holstein Kiel extended their unbeaten start to the season with a comfortable 3-0 win over Eintracht Braunschweig, who remain rooted to the bottom of the table after their fourth straight defeat, and are still waiting for their first goal of the season. Scoring has not been a problem for Kiel, though, and they showed that with their seventh of the season, Steven Skrzybski's strike going in off the post. He added his and Kiel's second, leaving Fejzic no chance with his shot on the turn, and Benedikt Pichler sealed the win, meeting Reese's cross for a goal which was confirmed after a lengthy offside check.

Karlsruhe 3-2 Sandhausen
Goals: 0-1 Kinsombi (10'), 1-1 Batmaz (32'), 1-2 Kutucu (61'), 2-2 Rapp (84'), 3-2 Cueto (87')

Karlsruhe recovered from falling behind twice to beat Sandhausen and register their first win of the season. David Kinsombi put the guests in front with an unchallenged run and finish from the edge of the area, but Karlsruhe levelled after half an hour when Malik Batmaz scored with a strikingly similar effort. Ahmed Kutucu gave the guests a somewhat fortunate lead after an hour, but after Simone Rapp brought the hosts level again, there was only going to be one winner at the BBBank Wildparkstadion. Lucas Cueto followed Rapp's example to spring from the bench and score the winner, drilling his effort unstoppably into the far corner.

Darmstadt 4-0 Hansa Rostock
Goals: 1-0 Tietz (3'), 2-0 Mehlmen (18'), 3-0 Tietz (54'), 4-0 Kempe pen. (74')

Philipp Tietz was at the double as Darmstadt made light work of Hansa Rostock to make it three wins from four for Torsten Lieberknecht's side. The first of Tietz's goals came just three minutes in as he pounced on a dawdling Markus Kolke and stabbed home, with the Rostock 'keeper caught completely unaware. Marvin Mehlmen's smart finish from the edge of the box made it 2-0 at half-time, before Tietz headed home from a corner to add a third less than 10 minutes after the break. Darmstadt's fourth came via the penalty spot as Tobias Kempe converted from 12-yards after substitute Oscar Vilhelmsson was uprooted in the box by a clumsy Ryan Malone tackle.

Fortuna Düsseldorf 2-2 Greuther Fürth
Goals: 0-1 Hrgota (43'), 1-1 Hoffmann (62'), 2-1 Kownacki (72'), 2-2 Hrgota pen. (78')

Two penalties at either end of the match bookended a thrilling draw in Düsseldorf. The hosts were first presented the chance to take the lead 10 minutes before the break, but Rouwen Hennings' spot-kick was denied by the feet of Greuther goalie Andreas Linde, who was awarded a free-kick from the resulting rebound as Hennings fouled the 29-year-old before stabbing over the line. Greuther were then level on the stroke of half-time as Branimir Hrgota latched onto Julian Green's excellent through ball and lifted beyond Kastenmeier and into the back of the net. Fortuna eventually found an equaliser with just under half an hour remaining thanks to Andre Hoffmann's towering header and they were ahead 10 minutes later with a second headed goal, this time courtesy of Dawid Kownacki. Unfortunately for Fortuna, Hrgota converted a late spot kick to ensure a share of the spoils.
