KANSAS CITY, Mo. — In his first game back on the field at Arrowhead Stadium in nine months, Patrick Mahomes was far from the sole standout in the Kansas City Chiefs’ commanding 31-10 season-opening victory over AFC West rival Denver Broncos on Monday night.
Instead, running back Kenneth Walker III, the reigning Super Bowl MVP who signed with the Chiefs in March, delivered a stellar performance in his Kansas City debut.
Editor’s Picks
The result was precisely the offensive boost the Chiefs envisioned, as Walker’s explosive speed and ball-carrying capability shoulder much of the load off Mahomes, who returned from surgery to repair torn ACL and LCL in his left knee, an injury sustained on Dec. 14. Across 26 touches, Walker powered through, around, and past the Denver defense in a spectacular showing, racking up 191 all-purpose yards and two touchdowns.
Walker converted on four short-yardage attempts, including a spectacular 60-yard touchdown on fourth-and-inches early in the third quarter. His performance made him only the third player since 2000 to rush for at least 100 yards in his Chiefs debut, joining Kareem Hunt (148 yards in 2017) and Clyde Edwards-Helaire (138 yards in 2020), per ESPN Research.
Denver never seized the lead and struggled to find any offensive rhythm with quarterback Bo Nix under center.
Nix, who was also returning from two offseason surgeries to repair a fractured right ankle that sidelined him during last year’s AFC Championship Game, struggled throughout the contest, including throwing an interception on Denver’s very first drive. The Chiefs defense sacked Nix four times, while speedy wide receiver Jaylen Waddle, one of Denver’s marquee offseason additions, was held to a single 2-yard reception.
Here are the key takeaways from the game for both sides:
What to make of the QB performance: While Mahomes was not flawless, his brilliance was more than enough to secure the victory over the Broncos. On the Chiefs’ opening drive, he showcased his trademark toughness and elite athleticism, scrambling out of the pocket in the red zone for a 15-yard touchdown run. According to Next Gen Stats, Mahomes reached a top speed of 15.8 mph on the play, 2.5 mph faster than his average rushing speed from a season ago. He found his rhythm in the second half, finishing the day with 184 passing yards and two touchdowns.
Most surprising performance: The Chiefs’ defense delivered a dominant performance, fueled by a wave of talented rookies. Rookie cornerback Mansoor Delane, the sixth overall pick, intercepted Nix to set up Kansas City’s first touchdown. Defensive end R. Mason Thomas contributed a sack, while defensive tackle Peter Woods consistently pressured the Denver backfield. Even second-year cornerback Nohl Williams provided excellent coverage on Broncos receiver Courtland Sutton, limiting him to just two catches for 11 yards. — Nate Taylor

The Broncos entered the season emphasizing the urgent need for a revitalized run game and a major impact from new wide receiver Jaylen Waddle.
Yet, their opening night quickly turned into a struggle on both fronts, as Denver’s ground game managed only 12 total rushing attempts on the evening.
Waddle did display glimpses of his potential impact during tight end Evan Engram’s first-quarter touchdown catch, which was set up by defenders leaning toward Waddle as Engram ran free. However, he finished the game with just one catch for 2 yards while the contest was still in reach.
This was not the start Denver envisioned. The team remains in search of a productive run game, and Waddle’s integration as a major offensive weapon remains a work in progress.
Most surprising performance: Despite holding Mahomes to 15-of-27 passing, the Broncos’ run defense was unable to contain Walker. He broke free for a 60-yard touchdown on Kansas City’s fourth play of the second half, racking up 149 yards up to that point and leaving a trail of missed tackles behind him. Walker finished with 173 rushing yards, a rushing touchdown, and a receiving touchdown, surpassing the single-game rushing total of any running back who faced Denver throughout the 2025 season.
What to make of the QB performance: Nix initially displayed an ability to bounce back early in the game. After taking a sack on the first play and throwing an interception on the third play from scrimmage, he led a flawless 5-for-5 touchdown drive on the team’s next possession. However, as the game wore on, he and the rest of the offense looked out of sync. Nix fumbled three times, losing one, alongside throwing another interception. This marked only the third lost fumble of Nix’s career, one of which occurred in the previous season’s opener.
Trend to watch: Running back J.K. Dobbins was a top rusher in the league before suffering a season-ending foot injury in a Week 10 victory over the Raiders last November. Head coach Sean Payton emphasized that re-signing Dobbins in the offseason was a top priority, as the Broncos had major plans for the 27-year-old back. While a single game does not define a season, in offensive coordinator Davis Webb’s first regular-season game calling plays, Dobbins received just three carries in the first half. The Broncos found themselves down two touchdowns before Dobbins finally received carries on consecutive plays.
Stat of note: Although Payton has previously described Nix’s capacity to avoid sacks as one of the quarterback’s key superpowers, the Chiefs brought him down four times on Monday. Nix was sacked more than twice in only two games a season ago — being sacked three times by the Raiders and four times by the Chargers in the regular-season finale. — Jeff Legwold
