Freiburg are up to second after their eighth victory of the season. Gregoritsch starred with a goal and an assist for Woo-Yeong Jeong's opener. The hosts have the second best defensive record in the Bundesliga right now having conceded just 13 times in their 13 games to date.
Schindler catches Lienhart in the face and that's a booking for the Cologne sub.
Christian Streich hugs each of his players coming off in this triple substitution. The Freiburg coach is looking extremely satisfied with his team's work today, and rightly so.
GREGORITSCH MAKES WAY
Huge applause for Gregoritsch, who goes off having scored and assisted in what is increasingly looking like three points for the hosts.
FREIBURG GOING SECOND
As things stand, Freiburg are going second in the Bundesliga standings, just one point behind leaders Bayern Munich. Cologne will be down in 12th at the end of Matchday 13, if things stay as they are here.
Steffen Baumgart has opted for a triple swap, with Thielmann, Schindler and Huseinbasic entering the fray.
Gregoritsch has scored three of his five goals this season with headers. Only Bremen's Niclas Füllkrug has managed to score as many headed goals this term.
Freiburg are in command now. Gregoritsch powers in a header to double the hosts' lead and Cologne are in trouble.
Maina is involved twice in quick succession as Cologne look to hit back. Flekken's error allows the midfielder in to shoot, with the former recovering to save. Maina then looks to cross from the near post but the ball stops underneath the Freiburg custodian, who gathers gratefully.
Cologne attack, Freiburg break. Gregoritsch plays in the perfect pass for Jeong to chase. The attacker takes a few strides forward before sending a shot across Schwäbe and in at the far post.
NO GO DOAN
Doan goes down in the area and there are shouts for a penalty. The referee waves away the protests and on we go.
GREGORITSCH HAS A GO
Gregoritsch wellies a left-footed shot that flies away from the target and ends up smacking Doan before going wide.
Away we go in the second half at the Europa-Park Stadion ...
It's all square at the break with both sides missing chances to edge in front.
This time the visitors really should be in front. The ball is presented to Skhiri right in front of goals, but the 27-year-old skies an effort miles over the crossbar. That was a let-off for the hosts.
Cologne go close to an opener. A corner from the right is headed across the goal by Tigges. Skhiri stretches and just fails to make contact.

KILIAN STOPS COLOGNE
Doan taps a pass in for Kübler, who smacks a shot at goal from close range. Kilian makes a superb sliding block and the defender is soon receiving a congratulatory hug from goalkeeper Schwäbe.
FREIBURG'S WING PLAY
Freiburg's attacks have mainly come down the right flank, where lively full back Lukas Kübler has crossed from three times.
After a frantic opening to this one, the pace has died down slightly, both sides catching their breath with a bit of keep ball.
Cologne survive a Freiburg attacking onslaught! Schwäbe saves brilliantly from Gregoritsch before the keeper then denies Grifo.
SCHWÄBE TAKES NO CHANCES
Günter gets a little too much power on his centre from the left but Marvin Schwäbe prefers to get a touch on it nonetheless, the keeper tipping the pass away from danger.
FLEKKEN SAVES FREIBURG
Kainz twists and turns inside the Freiburg box before firing one off to the far corner. Flekken is there with a one-handed, diving save to steer the ball away from danger.
GRIFO HAS A POP
Grifo slams one at the target but Schwäbe is there to make a two-handed save to keep this game level.
The hosts pile forward early on and a cutback finds Günter on the edge of the box. It's on his weaker right and he fires it into a defender.
BIG CHANCE FOR FREIBURG
With Union Berlin having just lost at Bayer Leverkusen, Bayern Munich are back on the Bundesliga summit. But it means Freiburg have a chance to go back into second place with victory here. Visitors Cologne are looking to move back into the top half of the table.
