The Kansas City Chiefs fell to the Dallas Cowboys, 28-17, on Sunday to move to 6-3 on the season.

Here are some quick facts following the loss.

1. Chiefs' quarterback Alex Smith put together an impressive performance

Smith completed 25 of 34 passes for 263 yards and two touchdowns on Sunday, compiling a 102.9 quarterback rating.

It was Smith's league-leading and career-high seventh game this season with a passer rating over 100.0.

Smith is tied for the second-most such games in a single season in franchise history and is just three such games shy of matching Len Dawson for the most in team history for a career.

2. Cowboys' quarterback Dak Prescott also continued his strong season

Prescott was impressive on Sunday, completing 21 of 33 passes for 249 yards and three total touchdowns (2 passing, 1 rushing).

Last season's Offensive Rookie of the Year, Prescott has followed his initial campaign with a strong sophomore season, posting a 97.9 passer rating.

He's shown an ability to score with both his arm and his feet throughout his brief career, as he did against Kansas City.

3. Prescott had a connection brewing with wide receiver Terrance Williams

Williams hauled in a career-high nine catches for 141 yards on Sunday, a season-high and the third-most of his career. His 77 yards after the catch were also a career-high.

It was the first time a Cowboys' player had tallied 100 yards through the air this season.

4. Smith's record-breaking streak without an interception came to an end

Facing a 4th-and-8 with just over five minutes to play and down a couple scores, Smith was picked off for the first time this season by Jeff Heath.

It snapped a streak of 297 passes without an interception dating back to last season, the second-longest streak in team history. Fittingly enough, Smith also owns the top spot on that list with 312 passes without a pick between the 2014 and 2015 seasons.  

Smith's streak this season set an NFL record, breaking the previous mark by one pass.

What makes the streak all the more incredible is that Smith leads the NFL in yards per attempt (8.34) and has attempted the second-most passes of 25-plus yards in the league (21). For context, that's over a full yard further per attempt than Kosar posted during his streak in 1991 (7.01), and Smith completed twice as many passes of over 25 yards than Kosar.

In addition, Smith's 18 passing touchdowns without a pick rank third all-time.

5. Tight end Travis Kelce hauled in five of those touchdowns, including one on Sunday

Kelce caught seven passes for 73 yards and a 2-yard touchdown against the Cowboys, marking his fifth touchdown grab of the year. That's more than he had all of last season, and it matches a single-season career-high (2014, '15).

6. Tyreek Hill had one of the crazier touchdowns you'll ever see

With just two seconds remaining in the first half, Smith hit Hill down the middle of the field as the Cowboys guarded the goal line in a prevent defense.

The thing is nobody tackled Hill, and thanks to a few key blocks and Hill's trademark speed, he scampered into the endzone for the score as time expired.

It went in the books as a 57-yard touchdown, which is (amazingly) just more of the same for the Chiefs this season. They've done it nine times already, doing so in seven of their nine games.

But to score like that at the end of a half? That's unique.

It was the longest half-ending touchdown in franchise history, according to the Elias Sports Bureau.

7. Hill is big play machine

Throwing to Hill in that situation makes sense considering his ridiculous knack for the long touchdown.

Three of those scores were from scrimmage this season, including Sunday's, tying Hill with a familiar face for the league-lead.

The play helped Hill surpass his total in receiving yards from last season, doing so with 22 fewer catches. The second-year receiver is currently averaging 49.3 yards per touchdown.

8. Sunday's matchup featured the two leading rushers in the NFL

Chiefs' rookie running back Kareem Hunt still leads the NFL in rushing through nine weeks this season with 800 yards, while Cowboys' running back Ezekiel Elliott ranks second with 783.

Elliott also ran for a touchdown on Sunday, matching Todd Gurley III for the most rushing touchdowns in the NFL (7).

9. Chiefs' kicker Harrison Butker remained perfect

Butker connected on a 38-yard field goal in the second quarter on Sunday, his lone attempt of the afternoon. It was Butker's 19th consecutive successful kick, moving him closer to history.

Ryan Succop (2011) and Pete Stoyanovich (1997-98) currently share the record with 22.

Butker is also just six kicks shy of the franchise record for successful kicks by a rookie. Succop currently holds the record, hitting 25 field goals in 2009.

10. Punter Dustin Colquitt made some history on Sunday, as well

Colquitt became just the second punter in franchise history to record 1,000 career punts. He's the 23rd player in NFL history to do so.
