The Bears outscored the Packers 24-21 during an entertaining and exciting second quarter Sunday night at Lambeau Field to take a 27-21 halftime lead.

But Green Bay rallied for 24 unanswered points in the second half en route to a 45-30 victory. As usual, star quarterback Aaron Rodgers fueled the Packers, completing 29 of 37 passes for 341 yards with four touchdowns and a 141.1 passer rating. His 341 yards were his most in 28 career starts against the Bears.

After an uneventful first period, the two teams combined for 45 points in the second, the most in any quarter in the history of the rivalry. The Bears' three touchdowns came on big plays: Justin Fields passes of 46 yards to Jakeem Grant Sr. and 54 yards to Damiere Byrd and Grant's 97-yard punt return.

Fields completed 18 of 33 passes for 224 yards with two TDs, two interceptions and a 70.8 passer rating and rushed for a game-high 74 yards on nine carries.

The Bears (4-9) have now lost seven of eight games since opening the season 3-2. They have now dropped six straight to the Packers, 11 of 12 and 21 of 24.

Here's what transpired in the game:

First half

The Bears took a 3-0 lead on Cairo Santos' 23-yard field goal with 4:21 left in the first quarter. They settled for the kick after Fields failed to connect with Cole Kmet in the end zone on third-and-goal from the 5.

The Bears widened the margin to 10-0 on their next possession on Fields' 46-yard touchdown pass to Grant. Fields took the shotgun snap and flipped the ball forward a few feet beyond the line of scrimmage to Grant, who sped around left end and raced down the sideline with a convoy of five blockers.

Unfortunately, the Bears' lead didn't last long. The Packers scored two touchdowns in a 1:03 span midway through the second quarter to take a 14-10 advantage.

First, Rodgers' 2-yard TD pass to Allen Lazard on fourth-and-goal cut the deficit to 10-7. Three plays later, Fields threw late to Darnell Mooney on an out pattern and safety Rasul Douglas intercepted the pass and returned it 55 yards for a score.

Remarkably, the Bears answered with two touchdowns of their own in a 1:49 span late in the first half to retake a 24-14 lead.

First, Fields responded to his miscue by throwing a slant pass to Byrd, who raced 54 yards for a touchdown. Green Bay's subsequent drive stalled at the 50 and Grant followed with a spectacular 97-yard punt return touchdown. Grant retreated to catch the ball at the 4, ran to his right and then reversed field to the left, taking advantage of a wall of blockers and racing down the left sideline.

The Packers climbed to within 24-21 on Rodgers' 38-yard TD pass to Davonte Adams with :44 left in the second quarter. But Khalil Herbert's 42-yard return of the subsequent kickoff helped set up Santos' 44-yard field goal as time expired in the first half, enabling the Bears to increase their lead to 27-21.

Second half

The Packers opened the second half with two Aaron Jones touchdowns in a 1:00 span, turning a 27-21 deficit into a 35-27 lead.

First, the Green Bay running back's 3-yard TD run capped a 9-play, 75-yard drive on the opening possession of the second half.

Two plays later, outside linebacker Preston Smith forced a fumble with a blindside sack of Fields that was recovered by outside linebacker Rashan Gary at the Bears 23. On the next snap, Rodgers lofted a 23-yard TD pass to Jones.

After a three-and-out by the Bears, Mason Crosby's 20-yard field goal gave the Packers a two-possession lead at 38-27 late in the third quarter.

Rodgers' fourth TD pass of the game, a 3-yarder to Adams, widened the margin to 45-27 with 4:33 remaining in the fourth quarter.

Santos provided the game's final points with a 43-yard field goal that closed the gap to 45-30 with 1:21 to play.
