Kansas City, Mo. ? This was one of those preseason games that sent both teams home with plenty to work on.

Philadelphia’s Brent Celek, left, and Ernie Sims team up to sack Kansas City quarterback Matt Cassel in the first half. The Chiefs suffered a last-second 20-17 loss to the Eagles on Friday in Kansas City, Mo.

Mike Kafka’s 18-yard pass to Riley Cooper in the closing seconds boosted the Philadelphia Eagles past Kansas City, 20-17, on Friday night, making Todd Haley 0-7 in preseason games as the Chiefs’ head coach.

But the quarterback picked to replace Philadelphia’s Donovan McNabb sputtered much of the night. And the Chiefs’ first five possessions produced a lost fumble, an interception, two three-and-outs and one first down.

“That wasn’t quite as sharp as we’d like it, that’s for sure,” Eagles quarterback Kevin Kolb said. “There are a lot of details we need to clean up so there needs to be some special attention to it starting with myself.”

Kolb was 11-for-25 for 103 yards. He got sacked four times and threw an interception and had a rating of just 39.2 — not exactly reminiscent of McNabb, the departed six-time Pro Bowler.

“Everybody had a little piece of that pie there,” coach Andy Reid said. “We will all learn some things from it and do better the next time.”

Chiefs rookie linebacker Cameron Sheffield was immobilized and had to be taken away on a cart after a helmet-to-helmet tackle on Mike Bell left him motionless on the field. Haley declined to discuss Sheffield’s status, but one player said he was moving.

It’s the second straight week the Chiefs have had a player removed like that on a cart. Last week it was cornerback Maurice Leggett, whose injuries are now said not to be career-threatening.

“Our thoughts, prayers are with Cameron Sheffield,” Haley said. “That’s two of those situations in two weeks. Right now I don’t have any information I feel comfortable in giving because again, there’s a lot of people out there that are family and friends of Cameron’s. I don’t want to say anything that ends up being wrong.”
