The Green Bay Packers and the Chicago Bears met at Lambeau Field in a clash between NFC North rivals.
The Packers were coming into the game off a four-game winning streak despite having a plethora of injuries while the Bears were equalling struggling with setbacks but came into the match with a 4-3 record.
On the first drive of the game, Packers quarterback Aaron Rodgers left the field with an injury which forced him out of the match and that was to be crucial as the Bears took advantage to secure a 27-20 win.
Read how all the action unfolded in our commentary below.
Good morning and welcome to the live commentary of the NFL clash between the Green Bay Packers and the Chicago Bears.
The Packers are flying high coming into this game following a four-game win streak, which has lifted them to the top of the NFC North.
Injuries have depleted Mike McCarthy's side but his side still find a way of winning games with quarterback Aaron Rodgers at the controls of his offense, which has destroyed the Minnesota Vikings and the Baltimore Ravens in the past two weeks.
The rushing of running back Eddie Lacy has given the Packers a major boost this season after selecting him in the second round of the 2013 Draft. He has amassed 446 yards on 112 carries, which puts his average per attempt at exactly four. He also has three touchdowns which has lifted the pressure off Rodgers somewhat, not that he needed it.
Talking of injuries the Bears have also had to deal with several of their own as quarterback Jay Cutler is out of action for this game along with linebacker Lance Briggs. Add them to Henry Melton, Nate Collins and DJ Williams who are all out for the year.
Despite these setbacks the Bears have remained competitive and a win at Lambeau Field in this game will shake up the pot in the NFC North for sure. Look for running back Matt Forte to have a big game behind impressive rookie offensive lineman Kyle Long against a less than stable Packers defensive front.
The inactives have been revealed and we'll start with the home side.
PACKERS INACTIVES: Harper, Nixon, Matthews, Perry, Boyd, Wilson, Finley.
BEARS INACTIVES: Cutler, Briggs, Anderson, Brown, Scott, Washington, Minter.
A big boost for Rodgers as wide receiver James Jones is fit to return to action following an lay-off with a knee injury for the past two weeks. He will bolster a depleted receiving corps which is without Randall Cobb and Jermichael Finley.
The Packers are still without All-Pro linebacker Clay Matthews, who pass rushing skills will be a big miss along with second year defensive end Nick Perry. CJ Wilson is also absent on the defensive line.
In the absence of Cutler, Josh McCown will start in his place for the first time since 2011. The 34-year-old has thrown 38 career touchdowns but has thrown 44 interceptions as well in his 12-year career.
The Bears still have a good offense without Cutler as they will be lead by Forte on the ground. But in the air McCown will have the option of throwing to Brandon Marshall, Alshon Jeffery and tight end Martellus Bennet. All of whom have made plays for the club this season.
The Bears will kick off so Rodgers will get the ball first.
Gould kicks the ball out of the endzone and Rodgers will start at the 20.
Immediately the Bears are penalised as they give up 15 yards for a facemask penalty with defensive tackle Paea guilty.
Rodgers fakes the handoff and fires over the middle to Nelson and he runs with the ball across the field for 26 yards to move his side to the Chicago 27.
Lacy keeps the chains moving to shift his side to the Chicago 11 with a 16-yard run over the left-hand side of the line as he found a hole and drove right through it.
SACK! Rodgers goes down for the sack inside the redzone as McClellin brings him down for a three-yard loss. Worryingly for the Packers Rodgers looks hurt as he gets to his feet. Hopefully it's nothing too serious. Crosby will attempt a 30-yard field goal to get them on the board.
FIELD GOAL GOOD!
Crosby fires his effort through the posts and gives his side the lead.
Hester returns the kickoff to the 29 where McCown will begin.
McCown throws on first down and he fires a strike over the right to Marshall who makes a good catch low at his feet to get the first down for his side with a 12-yard reception.
Another good throw by McCown as he fakes the handoff to Forte and fires the ball over the middle this for Marshall who makes the catch and races down the sideline before he's pushed out at the Green Bay 40 for a 19-yard gain.
BREAKING: Rodgers has headed inside to the locker room due to his apparent injury.
The Bears keep the chains moving with another good throw by McCown as he zips the ball out to Jeffrey on a wide receiver screen and he gets behind blocks from Bennett and Marshall to get 12 yards to move his side to the Green Bay 27.

Gould kicks the ball out of the endzone. Wallace replacing Rodgers will begin at the 20.

Lacy gets the yards he needs again with a four-yard carry to get his side another set of downs after Wallace completed his first pass of the game to White on a curl route for six yards down the right-hand sideline.
INTERCEPTION BEARS!

The Bears go three and out as McCown is forced to scramble on third down as he can't find an open receiver and Jones gets the sack for the Packers as he taps when he's on the ground.

TOUCHDOWN PACKERS!
The Packers take the lead as Wallace hands the ball off to Starks who bursts through the middle of the line and powers all the way into the endzone for a 32-yard score as Conte whiffed on the last-ditch tackle.
McCown will begin at his own 13 after Hester returns the ball for 14 yards.
The Bears move the chains as McCown fires two passes to Jeffrey for gains of 10 yards then 16 to move them out of the shadow of their own endzone. The 6ft 4in receiver muscled out the Williams to catch both passes with good strength.
Chicago's advance down the field is halted as Hyde breaks up a third down pass for Bennett forcing Podlesh to punt the ball away, this time he gets his kick off and Hyde returns the ball for no gain at his own 14.

McCown gets good protection from a four-man rush from the Packers and he fires an underneath pass for Forte, who carries the ball through several tackles and he gets to the Packers' 25 for a 33-yard gain.
The Bears move within inches of the goalline as McCown fires over the middle to Bennett on a crossing route and he evades the tackle of Hawk to get down to one before he's brought down. He thinks he has the touchdown but he is just short of the line.
TOUCHDOWN BEARS!
The Bears get their touchdown anyway as McCown hands the ball off the Forte on a draw play and he goes over the goalline for the one-yard touchdown. An excellent drive for the visitors.
Hyde returns Gould's kick to the 27 where Wallace will begin. Rodgers has still not returned.
CONFIRMATION: Rodgers is out for the rest of the game. A massive blow for the Packers, they will have to hope that isn't serious.

Wallace thinks he and Green Bay have another set of downs as he evades the rush in the pocket and throws on the run to Quarless on the left-hand sideline for eight yards but the tight end juggles the ball as he catches it and the officials rule the pass incomplete.

FIELD GOAL GOOD!

HALF TIME: Chicago Bears 17-10 Green Bay Packers
Green Bay couldn't have wished for a worse half of football as they trail the Bears by seven points and have lost Rodgers for the game and potentially longer pending on the severity of his shoulder injury.
It has become the battle of the backup quarterbacks as Wallace goes up against McCown and it's the Bears QB who is winning at the moment with some impressive play. He has been supported well by Forte and the ground game while Marshall has made some crucial catches, including one for a touchdown.
Wallace needs help from his receivers and the ground game as the contributions from Lacy have dried up since Rodgers left the match, if the Packers are going to get back into this.

FULL TIME: Chicago Bears 27-20 Green Bay Packers
The Bears close the gap at the top of the NFC North as three teams now have the same record in the division, and the Bears have the tie break over the Packers and the Detroit Lions hold the tie break over the Bears. That means the Lions lead the NFC North.
Chicago will be buoyed by their win as McCown showed brilliant poise in the pocket in the battle of the backup quarterbacks. He showed Wallace how to do it with an assured performance to lead the Bears to victory at Lambeau Field for the first time in six years.
The Bears will go into their clash with the Lions at the weekend with Cutler fit again and their hopes of reaching the playoffs this season bolstered.
Green Bay will be far more concerned with the loss of Rodgers than their defeat in this game. Reports suggest he has a broken collarbone which could leave him out for six weeks. That could have a disastrous effect on their playoff hopes this season looking at the play of Wallace at Lambeau.
Running backs Lacy and Starks did all they could to get their win for their side but in the end their multiple injuries on offense and defense took their toll. An serious injury to Rodgers could just be too much for them to overcome.
Thanks for joining our commentary. We'll be back on Friday morning with all the action from the clash between the Minnesota Vikings and the Washington Redskins.
