Isiah Pacheco’s MCL Sprain Puts Detroit Lions’ Backfield Plans on Hold

Core Event
Detroit Lions running back Isiah Pacheco suffered a sprained medial collateral ligament (MCL) during training camp, keeping him out of practice for several days and causing him to miss the team’s preseason opener against the Cincinnati Bengals. Head coach Dan Campbell said the injury is “a little bit” and expressed confidence that Pacheco will be ready when the regular season begins.
Background & Context
Pacheco joined Detroit in March on a one-year contract after completing his rookie deal with the Kansas City Chiefs. The Lions signed him to serve as the primary backup to newly extended running back Jahmyr Gibbs, following the trade of former starter David Montgomery to the Houston Texans. In Kansas City, Pacheco contributed to back-to-back Super Bowl victories (2022, 2023) before becoming injury-prone. He missed significant time in three of his four NFL seasons: a shoulder injury in 2023, a fractured fibula and rib issues in 2024, and an MCL sprain in 2025.
Data & Statistics
- 2025 (Lions): 13 games, 462 rushing yards, 1 rushing touchdown, 19 receptions for 101 yards, 1 receiving touchdown.
- Kansas City tenure (2022-2025): 2,537 rushing yards, 14 rushing touchdowns on 576 attempts.
- Injury record: missed a total of 17 games from 2023-2025 (equivalent to a full regular season).
- Pacheco’s 2023 season: 2 games missed (shoulder).
- 2024 season: 7 games missed (fibula fracture) plus additional rib injury time.
- 2025 season: 4 games missed (MCL sprain).
Official Statements & Responses
Coach Dan Campbell addressed the injury in a Monday press conference, describing the sprain as “a little bit” and emphasizing that the team feels “good” about Pacheco’s recovery timeline. He added that the Lions are not concerned about his availability for the start of the regular season. Campbell also highlighted the competition emerging among backup backs Jacob Saylors and Jabari Small while Pacheco recovers, noting that both players have shown promising progress in camp.

Why It Matters
Pacheco’s absence from preseason action limits the Lions’ ability to evaluate depth behind Gibbs before the regular season. The injury also underscores the risk the team assumed by signing a player with a recent history of knee problems. If Pacheco returns on schedule, he will provide a reliable second-down option; if the MCL issue lingers, Detroit may need to rely more heavily on Saylors, Small, or other depth players, potentially affecting the overall effectiveness of the running game.
What’s Next
The Lions expect to reassess Pacheco’s status during the final week of training camp and will determine his activation for Week 1 of the regular season. No further official timeline has been provided beyond the coach’s assurance that he should be ready when the season begins.
