The Detroit Lions are banking on a running back who was not even on the roster a year ago to provide crucial support for their star rusher. After placing Isiah Pacheco on injured reserve Tuesday with a back injury that will sideline him for at least four games, the Lions are turning to Jacob Saylors to spell Jahmyr Gibbs. Pacheco, a two-time Super Bowl champion with the Kansas City Chiefs, was signed this offseason to a one-year deal to replace David Montgomery, who was traded to the Houston Texans. Now, with Pacheco out, Saylors must step up. Saylors, 26, went undrafted in 2023 and has bounced around the league, spending time with the Cincinnati Bengals, Atlanta Falcons, Cleveland Browns, and New York Giants before landing on Detroit's practice squad in 2025. He played in 16 games last season, primarily on special teams, and carried the ball just twice for 11 yards. But his path to the NFL is unconventional: he earned All-UFL honors in 2024 while playing for the St. Louis Battlehawks, leading the league with 460 rushing yards in nine games. This preseason, Saylors turned heads. He rushed for 132 yards on 23 carries — a 5.7-yard average — and scored a touchdown. In the final preseason game against the Indianapolis Colts, he ran for 100 yards on 17 carries in a 25-16 win. Lions head coach Dan Campbell expressed confidence in Saylors' grasp of the offense. "I just like the thought of having a guy in our system, think that's important," Campbell told the Detroit Free Press. "He knows our terminology, knows our guys, knows the protections. Just kind of it knows it all, man. Understands our quarterback Jared Goff and how he thinks. I just think that's important." The Lions do not need to worry about Gibbs, a three-time Pro Bowler who tied for 11th in the NFL with 243 carries last season. But finding a reliable backup is critical. Montgomery ranked second on the team with 158 carries in 2024, providing Gibbs with crucial rest. Saylors must now fill that role, at least until Pacheco returns. Detroit opens the regular season at home against the New Orleans Saints on Sunday, September 13, at 1 p.m. ET on Fox.
