According to ESPN insider Adam Schefter, the 49ers are signing former Detroit Lions tailback Kerryon Johnson to their practice squad. He spent training camp with the Philadelphia Eagles.
Johnson, a former second-round pick, showed a lot of promise early in his career. Unfortunately, he was unable to become the prolific running back that Detroit thought he would. In 34 games with the Lions, Johnson rushed for 1,225 yards and eight touchdowns on 283 carries.
It'll be tough for Johnson to crack San Francisco's rotation at running back. If he does receive playing time this season, however, there's a chance that Kyle Shanahan's scheme could revitalize his career.
Johnson may need a few weeks before he's ready to suit up on Sundays for the 49ers. In the meantime, Shanahan will deploy Elijah Mitchell, JaMycal Hasty and Trey Sermon at running back.
Mitchell looked fantastic in his regular season debut with the 49ers, rushing for 104 yards and a touchdown. Sermon, meanwhile, was a healthy scratch from the lineup.
Losing a seasoned veteran like Mostert has to sting for San Francisco, but the team has more than enough options to keep its rushing attack afloat.
