Johnson, 24, burst on the scene with the Lions in 2018 after being selected in the second round out of Auburn. He impressed in the 10 games he appeared, averaging 5.4 yards per carry, and earned a spot as the team’s starting running back in 2019.
Knee injuries cut his 2019 campaign short after eight games, however, and he never really bounced back. Johnson rushed for just 181 yards last season before being waived by the Lions this offseason.
