The Detroit Lions will miss running back David Montgomery for the rest of the season after he suffered a ligament injury in his right knee Sunday during the 48-42 loss to the Buffalo Bills at Ford Field.
Head coach Dan Campbell said Monday that Montgomery will undergo season-ending surgery after suffering an injury to his medial collateral ligament (MCL) in the second quarter. He eventually limped off after staying in to block on a fourth-down conversion on Detroit's second touchdown drive.
Montgomery returned and had five touches in the second half, but primarily sat in favor of fellow starting running back Jahmyr Gibbs . Craig Reynolds and Sione Vaki are next on the depth chart.
Here's more on who will replace Montgomery for Lions fans and fantasy football manager alike:
Lions RBs: Who will replace David Montgomery
Jahmyr Gibbswill be the next man up in place of Montgomery. He becomes the featured running back of the offense, as he was in the second half against Buffalo. Gibbs, the No. 12 overall pick in 2023 out of Alabama, was on the field for 59 of Detroit's 79 offensive snaps (75%) with a higher percentage in the second half. He finished with eight rushes for 31 yards, five catches for 83 yards and two touchdowns.
Gibbs has consistently split time with Montgomery since both joined the Lions during the 2023 offseason. Gibbs, the former No. 12 overall pick, leads Detroit with 1,047 rushing yards with 11 rushing touchdowns and has added 395 yards and three touchdowns as a receiver.
Together, the two formed one of the most powerful running back duos in modern NFL history and took on the video game nickname of "Sonic and Knuckles." The two shared a relatively equal workload (185 carries for Montgomery, 186 for Gibbs) as runners for an offense that currently ranks sixth in the NFL in rushing (143.7 rushing yards per game) after yesterday's season-low output of 48 yards.
Across 29 regular season games and three playoff games, Gibbs has accounted for 2,941 total all-purpose yards (2,136 rushing and 805 receiving) as an explosive pop in Detroit's offense that leads the league in scoring.
Behind Gibbs, the Lions will rely on running backs Craig Reynoldsand rookie Sione Vakito handle any extra snaps in place of Montgomery.
Reynolds is a six-year NFL veteran who joined the Lions in 2021 as a backup option in the backfield and special teams contributor. In 2024, he has 12 carries for 51 yards, mostly in garbage time, and 562 yards on 131 carries in four years as a Lion.
The Lions traded up to draft Vaki in the fourth round of the 2024 draft. He has only carried it six times for 14 yards during mop-up duty in blowout wins but has become a standout contributor in nearly every phase of special teams . Vaki primarily played safety in college but played both ways as a senior, and Detroit took a shot on his ability as a playmaker on offense, while also enjoying his physicality from defense on kick coverages.

What Lions will miss without David Montgomery
Montgomery joined Detroit as a free agent on a three-year deal during the 2023 offseason. He signed a two-year extension this past October that'll keep him a Lion through the 2027 season.
Montgomery was a tone-setter in the backfield who'll be missed in the final three games of the regular season and in the NFL playoffs.
He finished 2024 with 775 rushing yards and 12 touchdowns on 185 carries as the starter who split snaps with Gibbs. His physical running style and ability to shed tackles will be missed, but the Lions still have a running back with the ability to hit home runs in Gibbs.
