bv. It’s Happening. Kansas City’s Offensive Engine Just Lost Two Vital Pieces Sunday’s game against the Bills. — And the League Is Watching.

KANSAS CITY, Mo. — In a league where depth charts are battle-tested weekly and superstars are only as good as their supporting cast, the Kansas City Chiefs are staring down a nightmare scenario. Two linchpins of their explosive offense—running back Isiah Pacheco and rookie left tackle Josh Simmons—have been officially ruled out for Sunday’s pivotal Week 9 clash against the Buffalo Bills. It’s not just a setback; it’s a seismic shift for a team gunning for another deep playoff run, and the ripple effects are already being dissected across the NFL landscape.
As the Chiefs (6-2) prepare to host the Bills (5-3) in a matchup dripping with AFC heavyweight implications, Kansas City’s coaching staff dropped the hammer on Friday: Pacheco’s knee injury from last week’s gritty win over the Washington Commanders will keep him sidelined week-to-week, while Simmons’ extended personal leave has ballooned into a three-week absence. For a unit that thrives on rhythm, protection, and burst, this feels like pulling the spark plugs from Patrick Mahomes’ high-octane engine. And yes, the league is watching—closely. How Andy Reid adapts could redefine the Chiefs’ season and send shockwaves through a crowded playoff race.

A Depleted Backfield: Pacheco’s Absence Hits Hard
Isiah Pacheco isn’t just Kansas City’s leading rusher; he’s the heartbeat of their ground game, the guy who turns third-and-long into first-and-goal with sheer grit. The fourth-year back exploded out of the gate this season, piling up 78 carries for 329 yards and a touchdown on the ground, while chipping in 11 receptions for 43 yards and another score through the air. His bruising style—think a human battering ram with afterburners—has been the perfect complement to Mahomes’ aerial wizardry, forcing defenses to respect the run and opening up the pass.
But Pacheco’s knee tweak against the Commanders ended his day early, and the Chiefs’ cautious approach means he’ll miss at least this tilt with Buffalo. His track record against the Bills is thin but telling: In a 2022 regular-season thriller, he managed just two carries for nine yards plus two catches for nine more. Now, with him out, the onus falls on a familiar face in the backfield.
Enter Kareem Hunt, the prodigal son who returned to Kansas City this offseason and immediately proved his worth. In Monday night’s victory over Washington, Hunt stepped up with nine carries for 40 yards and a touchdown, capping it off with a two-yard receiving score that had Arrowhead buzzing. The 30-year-old veteran knows the drill against Buffalo all too well—after all, he torched them for 17 carries, 64 yards, and a score in the 2024 AFC Championship Game. Over five regular-season meetings with the Bills, Hunt’s averaged a respectable 4.09 yards per carry on 34 attempts, though he’s yet to punch one in from the end zone.

Hunt’s no Pacheco clone—he’s more surgeon than sledgehammer—but his experience and pass-catching chops (hello, that AFC title run) could keep the chains moving. Still, the drop-off in explosiveness is real. Without Pacheco’s home-run potential, the Chiefs’ offense might lean heavier on Mahomes’ arm, a risky proposition against a Bills defense that’s already feasting on injuries in their own secondary.
The Blindside Blues: Simmons Sits, Moore Steps Up (With a Catch)
If the running game is Kansas City’s ignition, the offensive line is the chassis—and left tackle Josh Simmons was supposed to be the shiny new upgrade. Drafted in the first round of the 2025 NFL Draft out of Ohio State, the 6-foot-5 rookie flashed Pro Bowl promise in his first five starts, anchoring Mahomes’ blindside with poise beyond his years. But personal matters pulled him away after Week 5, and what was billed as a short hiatus has stretched into three weeks. The Chiefs’ brass insists it’s temporary, but whispers in the locker room suggest Simmons’ grip on the starting gig might be slipping.
Filling the void has been journeyman Jaylon Moore, who’s held his own in spot duty. Against the Commanders, Moore was dinged for one of three sacks on Mahomes (per Pro Football Focus) and surrendered a handful of pressures, but he didn’t crumble under Von Miller’s heat. Adequate? Sure. Elite? Not quite. And that’s the rub: In a game where Josh Allen’s Bills bring Von and a revitalized pass rush, even “adequate” might not cut it for a blindside protector.

Complicating matters further, Moore is listed as questionable with an illness, as is right guard Trey Smith (back). Both are expected to suit up, per the latest injury report, but in the NFL, “expected” is just another word for “fingers crossed.” If either falters, Kansas City could be shuffling their line like a deck of cards mid-drive—a recipe for chaos against a Bills front that’s already licking its chops.
Why the League Is Glued to This One
This isn’t hyperbole: The NFL’s eyes are locked on Arrowhead Stadium this weekend. The Chiefs sit atop the AFC West, but losses to the Bills could tighten a playoff bracket that’s suddenly wide open with the Ravens, Bengals, and Texans lurking. Buffalo, nursing their own injury woes (hello, missing cornerbacks and a gimpy edge rusher), sees this as a golden chance to steal momentum and hand Kansas City their first home loss of 2025.
Reid’s bag of tricks is legendary—expect creative personnel packages, maybe even a jet-sweep heavy set with Hunt in the mix—but the absences expose vulnerabilities in a team built for perfection. Can Mahomes Houdini his way through another blitz-heavy afternoon? Will Hunt channel his Cleveland ghosts into Buffalo nightmares? And when Simmons returns, does he reclaim his throne, or has Moore quietly auditioned for the long haul?
The answers start Sunday at 4:25 p.m. ET. For now, though, the Chiefs’ offensive engine sputters, and the league holds its breath. In a season of what-ifs, this feels like the ultimate test of Kansas City’s dynasty DNA. Buckle up—it’s going to be a wild ride.
