Kenneth Walker III Debuts with 173 Yards as Chiefs Rout Broncos

Mahomes acknowledged that his comeback began with significant rust: he started 2-of-10 and said he was “a little quick with my reads,” adding that he needs to trust both his offensive line and surgically repaired knee enough to remain in the pocket.
Mahomes’ opening-drive touchdown run provided an immediate physical test of his recovery; he wore a protective brace on his left knee and said the run helped restore his confidence that he could “go out there and be myself.”
The Chiefs’ emphasis on the running game was highly unusual for the Andy Reid–Mahomes era. NBC analysts Mike Florio and Chris Simms described giving Walker 23 handoffs as something Kansas City had never previously done in that era, saying the team looked different on both sides of the ball.
Andy Reid’s victory was his 18th in a season opener as a head coach, tying Bill Belichick for the NFL record.
The Kansas City Chiefs demolished the Denver Broncos 31-10 in their season opener, showcasing a dominant defense and a newly revamped running game that left NBC Sports analysts calling the team "different on both sides of the ball." Running back Kenneth Walker III, the reigning Super Bowl MVP who signed a three-year, $43.05 million deal with Kansas City this offseason, announced his arrival with 173 rushing yards and two touchdowns on 23 carries, including a 60-yard score. Quarterback Patrick Mahomes returned after nine months recovering from torn ACL and LCL injuries, throwing two touchdown passes and rushing for a 15-yard score despite acknowledging early rust in his comeback.
Kansas City never trailed and outgained Denver 392-176 in total yards, with the defense intercepting Broncos quarterback Bo Nix on Denver's opening drive and sacking him four times. The victory snapped a three-game losing streak against Denver and marked Andy Reid's 18th season-opening win as a head coach, tying Bill Belichick for the NFL record. Travis Kelce moved into second place on the NFL's all-time receiving-yards list among tight ends, trailing only Tony Gonzalez.
Kenneth Walker III delivered an immediate impact in his first game for the Chiefs, recording 191 total yards on 26 touches and scoring twice. WIBW noted that Walker ran for a career-high 173 yards on 23 carries, single-handedly outgaining the Broncos' entire offense. His 60-yard touchdown run in the third quarter showcased the explosiveness that made him Super Bowl LX's MVP with Seattle just months earlier. Walker's physicality allowed Kansas City to lean heavily on the ground game in a way rarely seen under the Andy Reid-Mahomes era.
The emphasis on the running game marked a dramatic shift for the Chiefs, who have historically relied on Mahomes' arm talent. Yahoo Sports pointed out that giving one running back 23 handoffs represented an unusual strategic decision for Kansas City's offensive system. By establishing Walker early, the Chiefs reduced pressure on Mahomes during his comeback and created lighter defensive boxes that opened passing lanes for the recovering quarterback.
Patrick Mahomes wore a protective brace on his left knee and completed 15 of 27 passes for 184 yards, two touchdown passes, and one interception. He started slowly, connecting on just 2 of his first 10 attempts, and admitted he was "a little quick with my reads" as he worked through post-rehab rust. Yahoo Sports reported that Mahomes needed to trust both his surgically repaired knee and his offensive line enough to stay in the pocket longer, a confidence issue that should improve with reps.
A key moment came on Kansas City's opening drive when Mahomes ran 15 yards for a touchdown, testing his knee in live action. He said that run helped restore his confidence that he could "go out there and be myself." The touchdown proved his injury recovery was progressing well enough to move in the pocket, though he acknowledged he needs more time to shed the rust that comes after nine months away from competition.
The Chiefs' defense set the tone immediately by intercepting Bo Nix on Denver's third play from scrimmage and sacking him four times throughout the game. KRCG highlighted that Kansas City held the Broncos to just 61 rushing yards, 9 first downs, and a total of 176 yards — fewer yards than Walker alone produced. This dominant performance ended Kansas City's three-game losing streak against Denver and proved the Chiefs have multiple ways to win beyond relying solely on Mahomes' individual brilliance.
Denver's offense struggled under first-year play-caller Davis Webb, with Nix managing just 131 passing yards while throwing one touchdown and one interception. The Broncos' inability to establish a running game or maintain offensive rhythm allowed Kansas City to build early leads and control the tempo. This defensive dominance, paired with Walker's rushing attack, suggests the Chiefs have significantly upgraded their roster from last season's 6-11 record.
Andy Reid earned his 18th season-opening victory as a head coach, tying the NFL record held by Bill Belichick. NBC Sports analysts Mike Florio and Chris Simms noted that Kansas City looked "different on both sides of the ball," with the running game representing a major tactical departure from the team's recent history. Reid praised Walker after the game, calling his performance "spectacular" and signaling confidence in the new dynamic with the elite running back sharing the offensive load with Mahomes.
The victory re-establishes Kansas City as the AFC West's dominant force after Denver snapped their nine-year division title streak last season. By demonstrating multiple paths to victory — a bruising running game, elite defense, and a recovering Mahomes — the Chiefs sent a message that they remain contenders despite last year's injury-plagued 6-11 campaign. As Kansas City heads into the season, the integration of Walker appears to have given the entire offense breathing room while Mahomes works through his post-injury adjustment.
