KANSAS CITY, Mo. (AP) — Alex Smith threw for 304 yards and a touchdown, Kareem Hunt ran for 91 yards and a score and the Kansas City Chiefs beat the Miami Dolphins 29-13 on Sunday to clinch back-to-back AFC West titles for the first time in franchise history. Tyreek Hill had six catches for 109 yards, and Harrison Butker converted five field goals, as the Chiefs (9-6) dashed what faint postseason hope the Dolphins (6-9) still harbored. Jay Cutler threw for 286 yards and a touchdown, but a chunk of that came on a 65-yard toss to Jakeem Grant late in the first half. Otherwise, Miami struggled against a Chiefs defense that has been stingy and opportunistic the past two weeks.

That’s coincided with the return of Marcus Peters from his disciplinary suspension. The Chiefs’ star cornerback had two interceptions and forced a fumble against the Chargers last week, a win that pushed them to the brink of the playoffs. He recovered a fumble and forced another on Sunday, giving Peters a hand in five turnovers the past two weeks. Both turnovers led to points, but they weren’t the Dolphins’ only costly miscues. They also were nailed for defensive holding four times, all of which came on three scoring drives for Kansas City. And the Dolphins inability to get off the field on third down, after holding opponents to 8 for 39 the past two games, was similarly deflating.

Still, the Dolphins had the ball trailing 17-13 late in the first half, the outcome and their longshot playoff hopes were still in the balance. But they soon went three-and-out and the Chiefs added a field goal to make it 20-13 at the break, then another to start the second half. Even when the Dolphins made a crucial stop on fourth down to get the ball back later in the third quarter, they squandered the opportunity. Peters stripped Kenny Stills to give the Chiefs the ball, and Butker hit his fourth chip-shot field goal for a 26-13 lead with 12:19 to go.

That gave a sparse crowd that turned out on Christmas Eve, braving slick roads from an overnight snowfall frigid wind chills at kickoff, plenty of time to celebrate a division title. Turn their thoughts toward a home playoff game in the new year, too. Chiefs TE Travis Kelce had four catches for 47 yards and a score , and has a catch in 63 straight games. … Chiefs coach Andy Reid improved to 5-1 against Miami. … Dolphins WR Jarvis Landry had five catches for 51 yards, giving him a league-best 103 catches this season. … The Dolphins had won seven of their last 10 against Kansas City. Their last loss at Arrowhead Stadium was in 2002.

Up next: The Chiefs head to Denver next Sunday to finish their regular season.

Here is the latest Mid-America sports news from The Associated Press

SIOUX FALLS, S.D. (AP) — Isaiah Moss and Maishe Dailey each scored 16 points, as Iowa pulled away for an 80-73 win over Colorado at the Sanford Pentagon. The Hawkeyes trailed 51-48 with under 12 minutes to play, but Cordell Pemsl converted a key bucket and Dailey knocked down a go-ahead 3-pointer _ one of only three converted in the game for Iowa _ to put the Hawkeyes in front for good 53-51 with 10:35 left.

CEDAR FALLS, Iowa (AP) — J.P. Macura scored 15 points and ninth-ranked Xavier hung on to beat host Northern Iowa 77-67 for its seventh straight win. Trevon Bluiett scored 12 points with seven rebounds for the Musketeers, who went on an 11-2 run down the stretch, highlighted by a Bluiett 3, to break open a tie game. Macura’s breakaway dunk and 3 in the final 95 seconds left sealed it for Xavier, which shot 12 of 23 from 3-point range.

LINCOLN, Neb. (AP) — James Palmer Jr. had 18 points and Nebraska opened up a 19-point lead midway through the first half and turned back a second half Delaware State surge to take an 85-68 win. Nebraska ran off 14 straight to go up 20-6 on Thomas Allen’s layup with 12:56 left in the opening half, and stretched that to 28-9 over the next four minutes.

KANSAS CITY, Mo. (AP) — Chiefs cornerback Marcus Peters says he chose to throw an officials’ flag in frustration during a loss to the New York Jets, so he had nobody to blame but himself for the resulting one-game suspension. Peters spoke briefly Friday for the first time since the incident three weeks ago. He returned last week to force three turnovers in a win over the Chargers.

KANSAS CITY, Mo. (AP) — Chiefs cornerback Marcus Peters says he chose to throw an officials’ flag in frustration during a loss to the New York Jets, so he had nobody to blame but himself for the resulting one-game suspension.

The Pro Bowl alternate spoke to reporters Friday for the first time since the incident three weeks ago, a full 2 minutes in which he also professed his affinity for cognac and plan to beat Miami on Sunday so Chiefs fans can “go home and put out the cookies and milk for Santa.”

Peters missed the Chiefs’ win over Oakland ago while serving coach Andy Reid’s suspension, but returned last week against the Chargers to pick off two passes and force a fumble in a 30-13 victory.

The win left the Chiefs needing only to beat the Dolphins to win the AFC West.
