The Kansas City Chiefs fell to the Dallas Cowboys, 28-17, on Sunday at AT&T Stadium to move to 6-3 on the year.
Chiefs' quarterback Alex Smith found tight end Travis Kelce for a go-ahead touchdown midway through the third quarter, but Dallas responded with a pair of unanswered touchdowns to pull away late.
Smith completed 25 of 34 passes for 263 yards and two touchdowns on the afternoon, including a 57-yard strike to wide receiver Tyreek Hill with just two seconds remaining in the first half.
It was Kansas City's seventh game this season with a touchdown of at least 50-plus yards.
Smith threw his first interception of the season late in the fourth quarter, snapping his streak of 298 pass attempts without a pick dating back to last season. He's one of just three players to ever toss 18-plus touchdowns before throwing an interception to begin a season.
The Chiefs will enjoy their bye week before traveling to New York on Nov. 19 to take on the Giants.
