NFL Week 18 betting preview

The Buffalo Bills host the New York Jets, and the Denver Broncos host the Los Angeles Chargers in the 4:25 p.m. ET window, with the Bills and Chargers also at 11 wins and locked into AFC wild-card positions. The Chargers are resting many of their starters, including Justin Herbert, which has resulted in the Broncos being 12.5-point favorites in the latest Week 18 NFL odds at Fanatics Sportsbook. Denver clinches the No. 1 seed with a win. The Bills are 12.5-point favorites, playing in their final regular-season game, and possibly final game ever, in their current stadium before a new stadium is ready for next season.

The Chicago Bears host the Detroit Lions at 4:25 p.m. ET, and although the Lions are eliminated from playoff contention, the Bears are still playing for seeding. Also, it's human nature for Bears head coach Ben Johnson, the former Lions offensive coordinator, to want to defeat his former team, especially after the Lions won their first matchup, 52-21. The Bears enter at 11-5 and have clinched the NFC North, while the Lions are 8-8 this year. Click here to sign up for Fanatics Sportsbook to bet and get up to $2,000 in No Sweat Bets in FanCash at Fanatics:
