GREEN BAY, Wis. — The Green Bay Packers earned a first-round postseason bye.

And they will need it.

Quarterback Aaron Rodgers aggravated a calf injury and missed two series but returned to help the Packers beat the Detroit Lions 30-20 Sunday in the de facto NFC North championship game at Lambeau Field.

With their record 24th consecutive home victory over the Lions, the Packers (12-4) captured their fourth straight NFC North title and a coveted bye. Green Bay will enter the postseason as the No. 2 seed in the NFC, with the defending champion Seattle Seahawks beating the St. Louis Rams on Sunday to earn the No. 1 seed and home-field advantage throughout the conference playoffs.

The Lions (11-5) play at the NFC East champion Dallas Cowboys in a wild-card game next weekend.

Rodgers was injured while throwing a second-quarter touchdown pass to wide receiver Randall Cobb. Rodgers, who hurt his left calf during the first quarter of last week’s win at Tampa Bay, scrambled to his right on first-and-goal from the 4. He appeared to re-injure the calf just before throwing the ball to Cobb in the end zone for a 14-0 lead.

A raucous Lambeau Field crowd quickly fell silent as the MVP candidate lay on the ground clutching his leg.

Backup quarterback Matt Flynn took the final possession of the first half, a handoff to run out the clock, and the first possession of the second half, a three-and-out punt. With Green Bay’s punt unit on the field, Rodgers came out of the tunnel to a loud ovation, walked to the sideline and started warming up.

In the meantime, Detroit drove 77 yards for touchdown in the final minute of the first half, then marched 51 yards for the game-tying touchdown in the third quarter. Quarterback Matthew Stafford converted a third-and-10 with a 12-yard completion to wide receiver Golden Tate and a fourth-and-1 with a sneak before throwing a 4-yard touchdown pass to wide receiver Calvin Johnson. Stafford and Johnson hooked up for a 20-yard score late in the second quarter.

Rodgers returned and immediately worked his magic with two big completions to Cobb. The first was a 29-yarder to the Lions’ 19. The second came on third-and-4, a 13-yard touchdown strike as Cobb caught the ball at the 10 on a crossing route against cornerback Cassius Vaughn and leapt into the end zone for the go-ahead score.

The Packers forced a three-and-out on the ensuing possession, and Rodgers drove the team into scoring possession. However, Detroit’s Isa Abdul-Quddus blocked Mason Crosby’s 52-yard field-goal attempt. However, the Lions couldn’t take advantage of excellent field position, as Stafford and running back Joique Bell flubbed the handoff on the first play of the ensuing possession.

The Packers made the Lions pay. Rodgers fired a 6-yard pass to tight end Richard Rodgers against linebacker Tahir Whitehead to convert a third-and-4, and a 15-yard completion to wide receiver Jordy Nelson set up Aaron Rodgers’ 1-yard sneak to make it 28-14 with 8:45 remaining.

Stafford was flagged for intentional grounding in the end zone, making it 30-14, but the Lions got the ball on the free kick. Stafford fired a 6-yard touchdown pass to running back Theo Riddick but, on review, Bell was deemed short of the goal line on the two-point play. That made it 30-20 with 1:45 to go and ended Detroit’s hopes.

Green Bay running back Eddie Lacy rushed for 100 yards on 26 carries — the first individual 100-yard game against Detroit’s top-ranked run defense this season.

The Packers drew first blood. After a bumbling goal-line possession in which they couldn’t punch it in on five snaps from the 1- or 2-yard line, Micah Hyde returned a punt 55 yards for a touchdown. He broke a tackle by Jed Collins and got big blocks from Brad Jones, Demetri Goodson and HaHa Clinton-Dix.

After Rodgers threw a 4-yard touchdown pass to Cobb to give the Packers a 14-0 lead with 2:24 left in the half, Stafford led a critical two-minute drill. On third-and-13, Stafford’s pass was deflected by Jones, but the linebacker clipped the side of Stafford’s helmet. The 15-yard penalty set up Stafford’s 20-yard bullet to Johnson for a touchdown with 24 seconds left in the half.
