Kehl is waiting to substitute Gundogan on the sidelines.
The game has picked up a lot of pace with both teams creating chances. Great entertainment at the BayArena.
SUBOTIC! Great intervention! Castro picked out Kiessling in the box, but the striker was dispossessed by Subotic with a fine sliding challenge.
HUMMELS! The free-kick was retaken, and Hummels headed once again from the same position with Castro outjumpped, but the ball flew wide of the left post.
GOAL! RULED OUT! Dortmund won a free-kick 40 yards from goal, Gundogan took it and picked out Hummels near the right post, who headed in. The referee, however, cancelled the goal, because he had not blown his whistle before the set-piece was taken.
Kuba replaced Kagawa a couple of minutes ago. The Japanese did not have the best of games, but forced a good save from Leverkusen's goalkeeper Bernd Leno.
Substitution Shinji Kagawa Jakub Blaszczykowski
Dortmund break away through Lewandowski and Perisic with the Polish striker releasing the Croatian down the wing, who in turn saw his cross blocked by Balitsch.
GOTZE IS SENT OFF! The attacker clashed with Balitsch, and as the defender was racing ahead, the Germany international sent a light push and a kick, which earned him a red card.
Yellow Card Hanno Balitsch
Red Card Mario Götze
KAGAWA! The Japanese attacker applied the final finish in a chaotic situation in the box, but Leno pulls off a tremendous save to prevent a goal.
Schmelzer manages to nutmeg Bender, but is hacked won by the midfielder and loses the ball.
Gotze is booked after sliding right into Leno, following a pass by Kagawa into the box. The Germany international could have done better to contract his right leg before crashing into the goalkeeper.
Yellow Card Mario Götze
With a numerical advantage now Dortmund are now charging forward. Renato Augusto, who had a great game, was replaced by Hanno Balitsch, who will slot in at right-back, while Gonzalo Castro will take the left-back slot.
Substitution Renato Augusto Hanno Balitsch
LENO! Immense save! Perisic hit the ball on the volley from inside the box, but the youngster, rooted to his spot, managed to pull off an impressive reflex save.
A twist of fate here as Dortmund not only escape seeing Hummels sent off, but also are now playing against 10-man Leverkusen.
STRAIGHT RED FOR KADLEC! The left-back with a horror lunge on Gotze on the right wing. Completely needless challenge by the defender, and a deserved red card.
Red Card Michal Kadlec
PENALTY? NO! SECOND YELLOW FOR HUMMELS? NO! Dubious decision by the referee as Hummels lunged on Renato Augusto with a reckless challenge just outside the box. Free-kick for Bayer Leverkusen.
Substitution Kevin Großkreutz Ivan Perisic
LEWANDOWSKI! Genius touch by the Polish striker as he released Kagawa through on goal, but Leno rushed and collected the ball from the Japanese's feet.
SCHURRLE! The ex-Mainz man was picked out by Sam, and turned with the ball before sending a superb shot for the right corner, which Weidenfeller collected easily.
Yellow Card Mats Hummels
Schurrle on the end of a horrible challenge by Schmelzer in the centre of the pitch, and is lucky to escape a yellow card here.
Dortmund are yet to create a clear chance on goal. The visitors have been lethargic so far.
Kiessling with an ambitious 30-yard shot, which flies well wide of Weidenfeller's goal.
Lars Bender is brought down by Gundogan in the centre of the pitch. The ex-Nurnberg, burdened with the task of replacing Nuri Sahin, who transferred to Real Madrid, has been almost invisible in this game so far.
SCHURRLE AGAIN! The attack with a marauding run down the right wing this time as he blew past four players before laying it for Sidney Sam, who hesitantly played a poo backpass, and it was intercepted.
SCHURRLE! The Germany international burst with speed down the left, leaving Hummels and Piszczek in his wake before delivery a low cross, which is cleared by Subotic.
The second half begins ...
End of the first half! RENATO AUGUSTO GETS BOOKED! The Brazilian, furious that the referee blew his whistle so early, kicked the ball, and earned himself a yellow card. Leverkusen have dominated the proceedings so far, forcing two superb saves by Weidenfeller through Schurrle and Reinartz. The reigning champions have been largely inefficient so far, and will have to step up their game in the second half, if they are to take anything from this match. Join us after the break for the second half.
Yellow Card Renato Augusto
SCHURRLE! Offside?! The ex-Mainz striker was released through on goal with a superb pass by Reinartz, but the linesman raised his flag for an offside. Difficult decision here.
Pool delivery from Gotze as the ball crossed the byline for a goal-kick.
Yellow Card Michal Kadlec
Yellow card for Kadlec as he commited a foul on Gotze from behind on the right wing. A harsh decision actually as there was not much contact between the players.
KIESSLING! The striker was picked on the edge of the box, lifted the ball, and hit it with a volley turn, but Weidenfeller made thee save.
Yet another foul by Rolfes as he brings down Lewandowski. The Germany international is walking a fine line with the referee.
Sam breaks free! OFFSIDE! Augusto released Kiessling with a superb flick, the striker in turned lifted a ball over Dortmund's defence to release Sam, but the ex-Kaiserslautern striker was flagged for an offside.
The game has become a bit scrappy in the last ten minutes or so as the two teams are locked in a very intense physical battle.
Gotze is brought down by Rolfes near the centre of the pitch. The Germany internationals have enjoyed quite a duel so far.
Gotze with a poor free-kick on the right as he tried to surprise Leno with an in-swinger from a tight angle, but failed to trouble the goalkeeper.
LEWANDOWSKI! The Polish striker broke free on the left, raced to the box, but was stopped by Toprak, who made a superb challenge.
Leverkusen have been the better team so far, and unlikely Dortmund, have created two clear chances. The visitors have Weidenfeller to thank for not lagging by two goals already.
REINARTZ! What a save by Weidenfeller! The defender was picked out in the centre of the box from a free-kick on the left, and sent in a bullet header, which the goalkeeper managed to parry! Superb block!
Bender with a super 25 yard pass to Schurrle on the right wing, who in turn teed it up for Sam just outside the box, and the ex-Kaiserslautern had his finish deflected for a corner on the right. This set-piece amounted to nothing.
Dortmund are yet to settle in the game as they are struggling to impose their style on Leverkusen.
Brave decision by Lewandowski as he meets the ball with his head with Rolfes' foot inches away from it. Free-kick to the visitors.
Schurrle and Kiessling attacking down the centre, but are soon crowded off the ball, allowing BVB to start a counter-attack.
Augusto! The Brazilian international sent an ambitious shot at Dortmund's goal from 30 yards out, but Weidenfeller claimed the ball easily.
Rolfes! The midfielder sent a header from inside the box just over the bar, following a free-kick on the right. Great chance wasted here.
Important thing to note is that the Bender twins are on the pitch today for the first time since their days at 1860 Munich. It promises to be one exciting midfield battle.
The subsequent corner-kick on the right amounted to nothing and now Dortmund are threatening to break free.
SCHURRLE! WHAT A CHANCE AND WHAT A STOP BY WEIDENFELLER! Renato Augusto released the ex-Mainz striker clear on goal on the right side of the box, but the Germany international saw his finish blocked by the goalkeeper!
Schmelzer fails to control a long ball on the left wing, and loses the ball to Castro.
Both teams playing carefully, waiting for a mistake by the opposition,
