Kenneth Walker III burst onto the scene with a 173‑yard rushing performance and two touchdowns in his first game, while Patrick Mahomes made his comeback from knee surgery as the Kansas City Chiefs routed the Denver Broncos 31‑10 on Monday night. Mahomes showed no signs of limitation from his repaired knee or the brace he wore, delivering 184 passing yards, two touchdown throws and even adding a rushing score of his own.
His all‑around display helped the Chiefs halt a three‑game losing streak against their division foe and snapped a nine‑year run as AFC West champions. Walker shouldered the ground game with 23 carries, posting the most rushing yards by a Chief since Jamaal Charles tallied 226 against Indianapolis 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.
Denver, on the other hand, looked lost offensively in the first game under new offensive coordinator Davis Webb. Bo Nix managed 131 passing yards but threw an interception and lost a fumble, and the Broncos managed just 176 total yards despite having splashed out in the offseason by trading a package of draft picks to Miami for wideout Jaylen Waddle. Waddle recorded a single catch for two yards, while veteran tight end Evan Engram led the Broncos with four receptions for 43 yards and their lone touchdown. The lingering question heading into the matchup 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.
He quickly erased any doubts when he capped the Chiefs’ opening drive with a 15‑yard touchdown run, demonstrating both confidence and mobility. Most of the heavy lifting on the ground, however, fell to Walker. The former Super Bowl MVP of Seattle, who inked a three‑year, $43.05 million contract this offseason, logged 14 carries for 89 yards in the first half alone, plus a couple of short passes out of the backfield.
After Denver tied the game on a 19‑yard touchdown pass from Nix to Engram, Walker kept the momentum alive, driving a 10‑play, 80‑yard drive that ended with Mahomes finding Rashee Rice in the end zone for a 14‑7 halftime lead. Early in the third quarter Walker turned a fourth‑and‑one situation into a spectacular 60‑yard touchdown run, giving Kansas City a 21‑7 advantage.
The teams later exchanged field goals: Brandon Jones intercepted Mahomes deep in Chiefs territory, setting up a short Wil Lutz kick, and Mahomes responded by connecting with Travis Kelce on a 59‑yard strike that set up Harrison Butker’s successful attempt. A pivotal moment arrived when Nix fumbled on the ensuing possession, allowing the Chiefs to seal the game.
Mahomes delivered a crucial 26‑yard pass to rookie running back Emmett Johnson on third down, positioning the offense at the Denver 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 for the final touchdown. Walker credited Mahomes’ presence as a key factor in his impressive debut, noting that having the league’s best quarterback on the field makes the running game considerably 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 had endured a season‑ending ACL and LCL injury last December, followed by immediate surgery and an intensive rehabilitation program. Any lingering concerns about his mobility were answered decisively with his 15‑yard touchdown scramble.
"If I was going to say I was nervous for anything, it was getting hit on it," Mahomes admitted. "But I just wanted to play. I've done so much rehab and so much 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 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 praised Mahomes, calling his performance "phenomenal" and noting that getting Patrick back in the mix helped knock the rust off the offense.
"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," Reid said.
The Chiefs’ dominant showing not only marked a triumphant return for Mahomes but also signaled a fresh start after missing the division title for the first time since 2015. With the offense clicking, the running game revitalized, and the defense making timely plays, Kansas City appears poised to contend for another AFC West crown.
