TAMPA, Fla. — The Green Bay Packers’ offense bounced back just enough to help them clinch a playoff spot as they beat the Tampa Bay Buccaneers 20-3 on Sunday at Raymond James Stadium.

The Packers rebounded from a 21-13 loss at Buffalo last week but did so largely behind their defense, which harassed Bucs quarterback Josh McCown all afternoon and allowed only 109 total yards.

Quarterback Aaron Rodgers, reportedly under the weather, finished the game with 318 yards and a late touchdown on 31-for-40 passing. Receiver Randall Cobb reeled in 11 passes for 131 yards, and Jordy Nelson had nine receptions for 113 yards and a touchdown.

Running back Eddie Lacy racked up 99 yards and a 44-yard touchdown on 17 carries as he surpassed the 1,000-yard mark on the season.

The Packers (11-4) will face the Lions next week at Lambeau Field in their regular-season finale.

The Buccaneers (2-13) have not won a game at home this season. They will play the Saints next week to wrap up the regular season and are still in contention for the No. 1 overall draft pick.

Playing in front of a large green-and-gold contingent on the road, the Packers got off to a sluggish start but broke through toward the end of the first quarter. Lacy took a pitch to Rodgers’ left, broke one tackle and rushed untouched into the end zone.

The Packers and Bucs traded field goals in the second quarter, as Mason Crosby connected from 42 yards out and Patrick Murray put Tampa Bay on the board as the first half expired.

Crosby tacked on a 25-yarder with 10:19 left to play, putting the Packers ahead by 10.

The Bucs’ offense looked punchless all day. With four minutes remaining in the first half, they had accumulated negative total yardage.

McCown completed 12 of 26 passes for 147 yards and an interception. He was also sacked seven times. Running back Doug Martin only managed 17 yards on the ground.

Still, Tampa Bay kept it close until Green Bay sealed the victory late in the fourth quarter. Rodgers capped a nine-play, 71-yard drive with a 1-yard touchdown pass to Nelson with 2:45 remaining.

NOTES: Green Bay has now reached the postseason six consecutive seasons under coach Mike McCarthy. … Bucs OT Anthony Collins was listed among the team’s inactive players for the third straight week Sunday after losing his starting left tackle job last week. Tampa Bay signed Collins to a five-year, $30 million deal in March, but his future with the team appears to be in doubt. … Packers OT Bryan Bulaga (concussion) was active. … Bucs LB Mason Foster (achilles) left the game in the first quarter and did not return. … General Martin E. Dempsey, the nation’s highest-ranking military officer, was at Sunday’s game as a special guest of the Bucs.
