SAN FRANCISCO (95.7 The Game) - After losing running back Raheem Mostert to a season-ending knee injury Tuesday, the 49ers elected to add former second-round back Kerryon Johnson to the practice squad.
Agent Drew Rosenhaus announced the agreement between both sides this afternoon, via ESPN's Adam Schefter.
Johnson appeared in 34 games over his three-year career with the Lions after they selected him in the second round of the 2018 NFL Draft out of Auburn. He rushed 283 times for 1,225 yards and eight touchdowns over that span.
In 2020, the 24-year-old appeared in all 16 games and had 52 carries for 181 yards and two touchdowns, while adding 19 catches for 187 yards and a touchdown.
Johnson was waived by the Lions in May and was promptly picked up by the Eagles. He was waived in August with an injury designation and went unclaimed on waivers.
Johnson will provide depth at the running back position behind Elijah Mitchell, Trey Sermon and Jamycal Hasty.
