The Buccaneers clinched the NFC South with a 27-19 comeback victory over New Orleans and earned the No. 3 seed when the Los Angeles Rams lost to Seattle 30-25.

Tampa Bay (10-7) will host Washington (12-5) in the wild card playoffs next Sunday night.

The Broncos (10-7) got the AFC’s seventh seed and will visit Buffalo (13-4) on Sunday.

Denver’s victory eliminated Cincinnati and Miami, which lost to the Jets.

Green Bay, which lost 24-22 to Chicago, will be the NFC’s seventh seed and visits No. 2 seed Philadelphia on Sunday in the middle game of a playoff tripleheader. The Eagles (14-3) beat the Packers (11-6) in the season opener, 34-29, in Brazil.

The Commanders beat Dallas 23-19 behind backup quarterback Marcus Mariota’s two touchdown passes.
