After the 49ers' thrilling 42-38 win over the Chicago Bears on Sunday night, the NFL announced its Week 18 slate and the 49ers will host the Seattle Seahawks on Saturday for a 5:00pm Pacific Time kickoff at Levi's Stadium.

The Seahawks and 49ers will battle for the NFC West crown and the conference’s top seed on Saturday at 5 p.m. on ABC & ESPN.

The San Francisco 49ers forced a regular-season finale against the Seattle Seahawks where the winner will claim the NFC's No. 1 seed and the NFC West title. The New England Patriots secured the AFC East title with the Buffalos Bills' dramatic loss to the Eagles.

Sunday’s finale will bookend a season that started with the 49ers in Seattle, eking out a 17-13 victory over the Seahawks as a late Brock Purdy touchdown to Jake Tonges earned them their first win of the season. Seattle has won 11 of its last 13 games to set up this showdown that will determine the NFC West.

The Patriots became the fourth team to clinch a division title, the Browns kept the Ravens alive and the 49ers moved closer toward a No. 1 seed.

The Seahawks’ chances at the one seed are greatly impacted by the outcome of the 49ers game on Monday Night Football.

The only active 49ers defenders to ever start a playoff game in their careers are safety Ji’Ayir Brown and cornerback Deommodore Lenoir.
