KANSAS CITY, Mo. (AP) — The Kansas City Chiefs were shut out for the third consecutive game in a Super Bowl rematch with Philadelphia on Monday night, allowing the Eagles to rally for a 21-17 victory. The Chiefs have scored just 53 points in the second half of games this season. They led 17-7 at halftime in a cold, driving rainstorm but were unable to make it stand up as Philadelphia beat old coach Andy Reid for the first time. The Chiefs had a chance at the go-ahead score inside the final two minutes, but Marquez Valdes-Scantling had a 51-yard pass fall through his hands at the goal line.
