Kenneth Walker III burst onto the scene with a spectacular debut, racking up 173 rushing yards and two touchdowns, while Patrick Mahomes made his long‑awaited comeback from knee surgery as the Kansas City Chiefs dispatched the Denver Broncos 31‑10 on Monday night. Mahomes, who wore a supportive brace on his surgically repaired left knee, appeared completely unencumbered, delivering 184 passing yards, two aerial scores and even a rushing touchdown, helping Kansas City halt a three‑game losing streak against their division foe and ending a nine‑year run as AFC West champions. Walker’s 23 carries produced the most rushing yardage by a Chiefs player since Jamaal Charles’ 226‑yard explosion against the Indianapolis Colts in 2012, the season preceding Andy Reid’s arrival as head coach.
The former Seattle Seahawks standout, signed in free agency, also contributed three receptions for 18 yards, showcasing his versatility out of the backfield. The Broncos, on the other hand, looked lost on offense in their first contest under new offensive coordinator Davis Webb. Quarterback Bo Nix managed 131 passing yards but threw an interception and lost a fumble, and the entire Denver offense mustered only 176 total yards.
Their high‑profile offseason acquisition, wide receiver Jaylen Waddle—obtained in a trade that sent a cache of draft picks to Miami—caught just one pass for two yards. Veteran tight end Evan Engram led Denver’s receiving corps with four catches for 43 yards and the lone touchdown. A central storyline heading into the game was whether Mahomes’ left knee, repaired nine months earlier after a devastating ACL and LCL tear against the Los Angeles Chargers, would hold up under the rigors of a full NFL season. The quarterback dispelled any lingering doubts when he capped the Chiefs’ opening drive with a 15‑yard touchdown run, a play that highlighted both his confidence and his physical readiness.
While Mahomes’ run was a headline moment, it was Walker who shouldered the bulk of the ground attack. The former Super Bowl MVP from Seattle, who inked a three‑year, $43.05 million contract in the offseason, delivered 14 carries for 89 yards in the first half alone, adding a couple of short receptions. When Nix connected with Engram on a 19‑yard touchdown pass to tie the game, Walker responded by powering through a fourth‑and‑one situation, then breaking free for a 60‑yard touchdown run to open the third quarter. The middle of the third quarter turned into a back‑and‑forth of big plays and field goals.
Denver safety Brandon Jones intercepted Mahomes deep in Chiefs territory, setting up a short Wil Lutz field goal. Kansas City answered quickly as Mahomes found Travis Kelce for a 59‑yard strike that set up Harrison Butker’s successful attempt. A subsequent fumble by Nix handed the ball back to the Chiefs, allowing them to seal the victory. In a creative play call, Mahomes handed the ball to rookie running back Emmett Johnson on third down for a 26‑yard gain, positioning the Chiefs at the Denver two‑yard line.
Andy Reid then employed an unconventional formation: Mahomes lined up in a three‑point stance beside backup quarterback Justin Fields, took the snap and handed the ball to Walker, who sprinted untouched into the end zone for the final score. Walker praised Mahomes’ presence as a catalyst for his own success, noting that the quarterback’s reputation forces defenses to respect the passing game, thereby opening lanes for the run game. "They have to key on Pat.
Pat’s the best quarterback in the league," Walker said. "He makes the run game a lot easier." Mahomes, who suffered a season‑ending knee injury in December of the previous year, underwent surgery and dedicated the offseason to an intensive rehabilitation program. He admitted that his biggest concern was taking a hit on his repaired knee, but his focus remained on simply getting back on the field. "If I was going to say I was nervous for anything, it was getting hit on it," Mahomes explained.
"But I just wanted to play. I’ve done so much rehab and so much work to put myself in this position.
This is what you do it for. My guys around me helped me. I didn’t play my best football and we went out and beat a really good football team pretty well, and it’s because the guys around me stepped up.
It’s just the start of it. We’re still so early in the season. It’s a great win but it’s just Week One." Head coach Andy Reid lauded Mahomes as "phenomenal," emphasizing how the quarterback’s return helped the team shake off rust and set a strong tone after missing the division crown for the first time since 2015.
"It was great to get Patrick back in the mix, knock a little rust off," Reid said. "I was proud of him and how he handled it, and he ran the ball a couple of times, and your hat goes off to the guy. Phenomenal." The victory not only gave Kansas City a decisive opening statement but also highlighted the synergy between a rejuvenated Mahomes and an emerging rushing attack anchored by Walker. As the Chiefs look ahead to a season that promises both challenges and opportunities, the confidence displayed in this Week One triumph suggests that they are poised to contend fiercely for the AFC West title and a deep playoff run.
