Isiah Pacheco Will Miss Lions’ First Four Games

Pacheco, 27, has been dealing with more than one issue since training camp began. He initially suffered an MCL sprain that limited his reps, then developed the back injury that ultimately forced Detroit’s hand. Head coach Dan Campbell had expressed cautious optimism as recently as August 27, saying Pacheco was “feeling better” while acknowledging the situation remained “touch and go.

That optimism didn’t hold. With twelve days left before Detroit’s opener against New Orleans, the Lions made the call to place Pacheco on IR rather than risk further injury by rushing him back. Under NFL rules, that guarantees Pacheco misses a minimum of four games — the season opener against the Saints, followed by matchups against Buffalo, the New York Jets and Carolina. His earliest possible return would be Week 5 against Arizona.

Why Detroit Signed Pacheco in the First Place

Detroit brought Pacheco in this offseason after trading David Montgomery to the Houston Texans, signing the former Chiefs back to a one-year, $1.81 million deal. Pacheco spent his first four NFL seasons in Kansas City, where he won two Super Bowl titles and racked up 2,537 rushing yards, 554 receiving yards and 17 total touchdowns. The plan was straightforward: pair a proven, physical rusher with Gibbs to give Detroit’s offense a true one-two punch in the backfield.

Instead, Pacheco’s first camp in Detroit has been defined by injury trouble rather than the tone-setting running style that made him a fan favorite in Kansas City. That’s a significant blow for a Lions offense built around wearing teams down on the ground.

Who Steps In Behind Gibbs

Detroit kept five running backs on its initial 53-man roster — Gibbs, Pacheco, Sione Vaki, Jacob Saylors and Jabari Small. With Pacheco sidelined, that job now falls to Saylors, a 2023 undrafted free agent out of East Tennessee State who carried the ball just twice as a rookie last season. Campbell expressed real confidence in Saylors this week, praising his grasp of Detroit’s system over raw traits. “I just like the thought of having a guy in our system, think that’s important,” Campbell said, via the Detroit Free Press. “Knows our terminology, knows our guys, knows the protections. Just kind of knows it all, man.

Detroit reportedly hosted veteran Kareem Hunt for a visit last week but has not signed him as of this update, leaving Saylors as the primary option behind Gibbs for the time being. Vaki and Small remain on the roster as depth, though neither has shown enough in limited NFL action to be considered a clear lock for meaningful touches.

What This Means for Jahmyr Gibbs

Any doubt about Gibbs carrying a massive workload this season disappeared the moment Pacheco landed on IR. Detroit’s offense already leans heavily on its star back, and now there’s no proven complement to spell him early in the year. Expect Gibbs to see an even heavier target share in both the running and passing game over these first four weeks, particularly in short-yardage and goal-line situations that Pacheco was specifically brought in to handle.

For fantasy managers, this is about as clean a workload boost as you’ll find heading into Week 1. Gibbs was already a top-tier pick before this news; he’s arguably a locked-in top-three running back option now that Detroit’s backfield depth chart runs through an undrafted second-year player with two career carries.

End Of Isiah Pacheco Rant

Detroit’s backfield plan for 2026 didn’t survive training camp intact, and that’s a real problem heading into a season with real expectations. Losing Pacheco for a month robs the offense of exactly the physical, load-bearing runner it signed him to be, and it puts real pressure on Saylors to prove he belongs in a much bigger role than anyone expected in August.

The silver lining, if there is one, belongs to Gibbs and to anyone who drafted him. Detroit’s schedule to open the season isn’t especially punishing, which gives Saylors a reasonable runway to develop before tougher matchups arrive.

Pacheco’s earliest possible return lines up with Detroit’s Week 5 game against Arizona, right before the Lions’ Week 6 bye. Whether he’s ready by then, and whether Saylors has done enough to change the backfield picture entirely, are both questions Detroit won’t be able to answer for several weeks.
