PHILADELPHIA -- The Chiefs took advantage of Philadelphia Eagles mistakes, including three interceptions, to give Kansas City coach Andy Reid a 26-16 victory in his return to the city where he worked for 14 NFL seasons.
One of the interceptions, by safety Eric Berry, was returned 38 yards for a touchdown in the first quarter.
Kansas City's defense shut down new Eagles coach Chip Kelly's vaunted offense, which had scored more than 30 points in each of the first two games.
Most of the pregame focus was on Reid and his return to South Philadelphia, but once the game started, the big story was the five Eagles turnovers that gave the Chiefs 13 of their 26 points.
And now the focus is on Kansas City's 3-0 record. The Chiefs have already won more games this season than they did last season, when they finished 2-14.
Kansas City took a 16-6 halftime lead before the Eagles (1-2) kicked a third-quarter field goal to cut the lead to a touchdown.
The Chiefs drove 62 yards in eight plays and scored a touchdown on a 3-yard run by running back Jamaal Charles to make it 23-9 with 12:57 to play.
On Philadelphia's next possession, running back LeSean McCoy gave the Eagles hope when he scored on a 41-yard dash to make it 23-16 with 11:36 left. However, the Chiefs put together a clock-draining drive -- 15 plays in 8:15 -- that ended with Ryan Succop's fourth field goal of the game and finished the Eagles' chances of a comeback.
Chiefs quarterback Alex Smith completed 22 of 35 passes for 273 yards. Donnie Avery made seven receptions for 141 yards, and Charles ran 20 times for 92 yards.
Eagles quarterback Michael Vick went 13-for-30 for 201 yards with one touchdown pass and two interceptions. Vick also ran five times for 95 yards. McCoy gained 158 yards on 20 carries.
The Chiefs took a 3-0 lead after a muffed punt return by Damaris Johnson gave them the ball on the Philadelphia 8.
The Eagles then gave the Chiefs a gift, and this time the Kansas City offense didn't have to worry about punching it in. A pass from Vick was batted into the air by Chiefs linebacker Derrick Johnson, and safety Berry grabbed it and returned the interception 38 yards for a touchdown. That made it 10-0 with 11:12 left in the first quarter.
At that point, the Chiefs had a net offense of minus-4 yards.
The Eagles got six points back late in the first quarter, thanks to two big plays. Vick broke free up the middle and ran for 61 yards -- the longest run of his career -- to the Kansas City 26. One play later, Vick threw a perfect pass -- and took a big hit -- to wide receiver Jason Avant in the corner of the end zone. Kelly elected to go for the two-point conversion, and tight end Zach Ertz tried to run it in but was stopped short, so the Eagles trailed 10-6 with 5:06 left in the first quarter.
Kansas City added two field goals before halftime and both came after big plays by wide receiver Donnie Avery. His 51-yard catch-and-run set up Succop's 31-yard field goal and his 26-yard catch set up Succop's 34-yarder that gave the Chiefs a 16-6 lead with 2:27 left in the first half.
NOTES: Former Eagles quarterback Donovan McNabb was honored during halftime ceremonies when his No. 5 was retired. Only eight other Eagles have had their number retired. The most recent was Brian Dawkins' No. 20 last year. ... Chiefs OT Mike DeVito left the game in the second quarter with a neck injury. ... Bradley Fletcher was back at left cornerback for the Eagles after missing Sunday's loss to San Diego with a concussion.
