Chiefs vs. Broncos halftime update: Kansas City trails Denver, 21-3

The Kansas City Chiefs trail the Denver Broncos, 21-3, at halftime of the regular season finale between the two teams at Sports Authority Field at Mile High in Denver, Colo. on Sunday.

Broncos quarterback Peyton Manning threw two touchdown passes to wide receiver Eric Decker and completed 17-of-22 passes for 218 yards, but it was a heads-up defensive play that, for a while at least, stood out as the most important of his first half accomplishments. After Broncos running back Ronnie Hillman fumbled late in the first quarter, Manning made a touchdown-saving tackle on, or at least got in the way of, Kansas City's Brandon Flowers on the scoop-and-return. Denver went on to hold the Chiefs to a field goal, preserving its early lead.

As for the Chiefs, they failed to convert on two red zone opportunities, with placekicker Ryan Succop missing a field goal later in the second quarter, keeping his team from pulling to within 7-6 at the time. Denver took advantage of the field position created by the miss, marching down field to take a two-score lead.

Chiefs quarterback Brady Quinn finished the half 6-of-11 for 44 yards, while running back Jamaal Charles gained 34 yards on nine carries. Kansas City was outgained by Denver, 277 total yards to 89, in the half.
