Fliff promo code: Bills vs. Chiefs odds and preview Kickoff from Kansas City’s GEHA Field at Arrowhead Stadium is set for 6:30 p.m. ET on CBS and Paramount+. Entering the weekend, the AFC’s top-seeded Chiefs (16-2) were posted as 2-point favorites over the second-seeded Bills (15-4) with a game total of 48.5 points. Mahomes and the two-time-defending Super Bowl-champion Chiefs beat the visiting Houston Texans 23-14 last weekend after getting a wild card-round bye. Allen’s Bills, meanwhile, have advanced with home wins over Denver Broncos (31-7) and Baltimore Ravens (27-25). Host Buffalo beat K.C. 30-21 in Week 11 this season, but the Chiefs have won all three playoff meetings since 2020. Another victory Sunday will send coach Andy Reid’s team to Super Bowl 59 in New Orleans and put the Chiefs a win away from the NFL’s first Super Bowl Era three-peat. The Bills, meanwhile, are seeking their first Super Bowl appearance since the 1993 season and the franchise’s first Lombardi Trophy.
