Ravens' win streak at nine

Lamar Jackson threw three touchdown passes and the Baltimore Ravens became the AFC's first team to clinch a playoff berth following a 24-17 victory over the host Buffalo Bills on Sunday.

"I tried to make a big deal out of it in the locker room, and the guys kind of gave me a smattering of applause," said coach John Harbaugh, who led Baltimore to its eighth playoff berth in his 12 seasons. "They've expected that and I think they earned the right to expect that."

Baltimore extended its franchise-best winning streak to nine and improved to 11-2.

The bulldozing Ravens offense was mostly held in check. Baltimore was held to a season-low 257 yards, and punted seven times for an offense that entered with only 24 punts on the season.

With 40 yards rushing, Jackson upped his total to 1,017, 23 short of breaking the single-season record for quarterbacks set by Michael Vick in 2006.

Buffalo drove down into the red zone on its final possession but fourth-and-8 at the Baltimore 16, Josh Allen's pass over the middle intended for John Brown was broken up by Marcus Peters at the goal line.

Buffalo (9-4) had a three-game winning streak end but remains in control of its playoff future as the Bills continue to hold down the first of the AFC's two wild-card spots.

Denver 38, Houston 24: Rookie Drew Lock threw for 309 yards and three touchdowns, Kareem Jackson had an interception and returned a fumble 70 yards for a touchdown against his former team and the Broncos (5-8) stunned the host Texans (8-5).

Chargers 45, Jacksonville 10: Philip Rivers threw for 314 yards and three touchdowns, including an 84-yarder to Austin Ekeler that was the longest completion of the quarterback's 16-year NFL career, and the Chargers (5-8), who play host to the Vikings next week, handed the host Jaguars (4-9) their fifth consecutive lopsided loss.

N.Y. Jets 22, Miami 21: Sam Ficken kicked a 44-yard field goal as time expired after the host Jets (5-8) benefited from a pass interference call determined by the league's officiating office and avoided a season sweep by the Dolphins (3-10).
