Kenneth Walker III burst onto the scene with a spectacular debut, rushing for 173 yards and finding the end zone twice, while Patrick Mahomes made his much‑anticipated comeback from knee surgery as the Kansas City Chiefs routed the Denver Broncos 31‑10 on Monday night. Despite wearing a supportive brace, Mahomes showed no signs of lingering discomfort. He threw for 184 yards, delivered two passing touchdowns, and added a rushing score of his own, helping Kansas City break a three‑game losing streak against their division rival and ending a nine‑year streak as AFC West champions.
Walker’s 23 carries marked the most rushing yards by a Chiefs player since Jamaal Charles’ 226‑yard performance against the Indianapolis Colts in 2012, the season before Andy Reid took over as head coach. The former Seattle star, who signed with Kansas City in free agency, also contributed three receptions for 18 yards. The Broncos, on the other hand, struggled mightily on offense in coordinator Davis Webb’s first game calling plays.
Quarterback Bo Nix managed 131 passing yards but threw an interception and lost a fumble, leaving Denver with just 176 total yards of offense. This was despite the high‑profile trade that sent a package of draft picks to Miami for wide receiver Jaylen Waddle.
Waddle recorded a single catch for two yards, while tight end Evan Engram led Denver with four receptions for 43 yards and the lone touchdown. A lingering question heading into the matchup was how Mahomes’ surgically repaired left knee would hold up nine months after the ACL and LCL injury he suffered against the Chargers last December. The quarterback erased any doubts early, capping the Chiefs’ opening drive with a 15‑yard touchdown run.
The bulk of the ground game, however, belonged to Walker. The former Super Bowl MVP, who inked a three‑year, $43.05 million contract this offseason, tallied 14 carries for 89 yards in the first half alone, supplementing his rushing with a few short receptions out of the backfield. Denver briefly tied the game when Nix connected with Engram on a 19‑yard touchdown pass, but Walker kept the momentum swinging for Kansas City. He powered through a 10‑play, 80‑yard drive that concluded with Mahomes finding Rashee Rice—still recovering from his own knee injury—for a 15‑yard touchdown reception, putting the Chiefs ahead 14‑7 at halftime.
The third quarter opened with a spectacular play from Walker. On a fourth‑and‑one situation, he burst through a defender for a 60‑yard touchdown run, extending Kansas City’s lead. Both teams exchanged field goals later in the quarter, highlighted by a Brandon Jones interception of Mahomes deep in Chiefs territory that set up Wil Lutz’s chip shot, and a 59‑yard Mahomes‑to‑Travis Kelce connection that led to a Harrison Butker field goal. A critical turnover followed when Nix fumbled on the ensuing possession, giving the Chiefs a chance to seal the game.
Mahomes delivered a 26‑yard pass to rookie running back Emmett Johnson on third down, moving the ball to the Denver two‑yard line. Andy Reid then employed a trick play: Mahomes lined up in a three‑point stance alongside backup quarterback Justin Fields, snapped the ball, and handed it to Walker, who sprinted untouched into the end zone for the final touchdown. Walker praised Mahomes’ presence as a catalyst for his own breakout performance. “They get to key on Pat.
Pat’s the best quarterback in the league,” Walker said. “He makes the run game a lot easier.” Mahomes, who endured a season‑ending ACL and LCL injury last December, underwent surgery and dedicated the offseason to a rigorous rehabilitation program. When asked about his nerves, he admitted, “If I was going to say I was nervous for anything, it was getting hit on it.
But I just wanted to play. I’ve done so much rehab and work to put myself in this position.
I just wanted to play.” He added, “This is what you do it for. My guys around me helped me.
I didn’t play my best football, but we went out and beat a really good 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 the quarterback’s ability to shake off rust and make an immediate impact.
“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 sent a clear message to the rest of the AFC West: Kansas City is back in contention, and Mahomes’ return signals a resurgence for an offense that had sputtered in recent seasons. With the season only beginning, the Chiefs look poised to challenge for the division title they missed for the first time since 2015.
