Kenneth Walker III burst onto the scene with a spectacular debut, racking up 173 rushing yards and crossing the end zone twice, while Patrick Mahomes made his first appearance since undergoing knee surgery as the Kansas City Chiefs dispatched the Denver Broncos 31-10 on Monday night. Mahomes appeared completely unencumbered by his recent operation or the protective brace he wore, delivering 184 passing yards, two touchdown throws and adding a rushing score of his own, helping Kansas City halt a three‑game losing streak against their division rivals and ending a nine‑year run as AFC West champions. Walker shouldered the ground game with 23 carries, posting the most rushing yards by a Chiefs player since Jamaal Charles tallied 226 against the Indianapolis Colts in 2012, the season just before Andy Reid assumed head‑coaching duties.
The former Seattle star, who arrived in Kansas City as a free‑agent, 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 with new offensive coordinator Davis Webb calling the plays. Quarterback Bo Nix managed only 131 passing yards, threw an interception and lost a fumble, while the entire Broncos offense produced a meager 176 total yards.
Their high‑profile offseason acquisition, wide receiver Jaylen Waddle, who was obtained from Miami in a trade involving multiple draft picks, recorded a single catch for two yards. Tight end Evan Engram led Denver’s receiving corps with four grabs for 43 yards and the lone touchdown of the night.
A lingering question heading into the game was whether Mahomes’ surgically repaired left knee would hold up after nine months of recovery following the ACL and LCL injury he suffered against the Chargers last December. The quarterback dispelled any doubts early, capping the Chiefs’ opening drive with a 15‑yard touchdown run that demonstrated both his confidence and his mobility. While Mahomes’ run was a highlight, it was Walker who dominated the rushing attack. The Super Bowl MVP from Seattle, who signed a three‑year, $43.05 million contract this offseason, logged 14 carries for 89 yards in the first half alone, plus a couple of receptions out of the backfield.
Denver briefly tied the game when Nix connected with Engram on a 19‑yard touchdown pass, but Walker’s relentless pounding set up a 10‑play, 80‑yard drive that culminated in a 15‑yard touchdown reception by Mahomes to Rashee Rice, who, despite his own recent knee injury, managed to evade two defenders and reach the end zone, giving Kansas City a 14‑7 lead at halftime. The third quarter opened with Walker turning a fourth‑and‑one situation into a spectacular 60‑yard touchdown run, instantly putting the Chiefs ahead by 21‑7.
The teams exchanged field goals later in the period, highlighted by a Brandon Jones interception of Mahomes deep in Kansas City territory that set up a short Wil Lutz kick, and a 59‑yard strike from Mahomes to Travis Kelce that positioned Harrison Butker for another successful field goal. A critical turnover by Nix on the following possession allowed the Chiefs to seal the game.
Mahomes found rookie running back Emmett Johnson on third down for a 26‑yard gain, moving the ball to the two‑yard line. Reid then employed a trick play: 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 key factor in his dazzling debut, noting that the quarterback’s leadership makes the running game easier. "They got to key on Pat.
Pat's the best quarterback in the league," Walker said. "He makes the run game a lot easier." Mahomes, who missed the remainder of last season after a season‑ending ACL and LCL injury, underwent surgery and devoted the offseason to an intensive rehabilitation program. He admitted he was nervous about taking hits on his repaired knee, but emphasized his eagerness to play.
"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," noting that the quarterback’s return helped the team shake off rust and reestablish its offensive identity after missing the division title for the first time since 2015. "It was great to get Patrick back in the mix there, 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 statement win to open the 2026 NFL season but also signaled that Mahomes’ knee is holding up and that the Chiefs’ offense can once again operate at an elite level. With Walker’s breakout performance and Mahomes’ seamless return, the Chiefs look poised to contend for the AFC West crown and perhaps another Super Bowl appearance.
