KANSAS CITY, Mo. -- Alex Smith threw for 225 yards and two touchdowns, and the Kansas City Chiefs held off the scrappy Cleveland Browns late in the fourth quarter to preserve a 23-17 victory Sunday and remain the NFL's lone undefeated team.
The Chiefs (8-0), off to their best start since 2003, built a 20-7 lead late in the first half before the Browns (3-4) made it a game.
Jason Campbell, starting in place of the ineffective Brandon Weeden, threw for 293 yards and two touchdowns for the Browns.
The second scoring pass, a 17-yarder to Fozzy Whittaker out of the backfield, got Cleveland within a field goal early in the third quarter.
The Chiefs kept stopping the Browns down the stretch, though. They forced a turnover on downs with just over 2 minutes left, and Ryan Succop kicked his third field goal in the closing seconds to help seal the victory (see full recap).
Patriots rally after horrid start
FOXBOROUGH, Mass. -- The New England Patriots shook off a dismal first half and another mediocre performance by Tom Brady to beat the Miami Dolphins 27-17 on Sunday.
Trailing 17-3 after gaining just 59 yards in the half, the Patriots quickly turned the game around in the third quarter with two touchdowns in a span of seven plays.
The Patriots (6-2) outscored the Dolphins (3-4) in the third quarter 17-0. Miami lost its fourth straight game.
Brady completed 13 of 22 passes for just 116 yards, but threw a 14-yard touchdown pass to Aaron Dobson with 6:32 gone in the third quarter that began the comeback (see full recap).
Andy Dalton torches Jets
CINCINNATI -- Andy Dalton threw a career-high five touchdown passes -- four of them to Marvin Jones -- as the Cincinnati Bengals drubbed the New York Jets 49-9 on Sunday, their first dominant performance of a promising season.
Jones set a Bengals record for touchdown receptions, scoring on catches of 9, 6, 17 and 6 yards.
Dalton's five touchdown passes gave him 11 in his last three games, his best such span. He's the first quarterback to throw for five TDs against the Jets since Dan Marino in 1988.
The Bengals (6-2) won their fourth in a row and padded their AFC North lead.
New York (4-4) took its most lopsided loss since 2010. Rookie quarterback Geno Smith threw two interceptions that were returned for touchdowns (see full recap).
49ers rout Jaguars in London
LONDON -- Colin Kaepernick ran and threw his way to victory Sunday, leading the San Francisco 49ers over the Jacksonville Jaguars 42-10 at Wembley Stadium.
Kaepernick threw for 164 yards and one touchdown, and ran for 54 yards and two touchdowns. Frank Gore also ran for two scores.
The 49ers improved to 6-2 with the win, their fifth in a row, while the Jaguars remained winless at 0-8.
It was the eighth regular-season NFL game at Wembley, the home of England's national soccer team, and the second this year. The Minnesota Vikings beat the Pittsburgh Steelers 34-27 last month (see full recap).
