On Saturday, the 49ers activated running back Kerryon Johnson from their practice squad, moving running back JaMycal Hasty and defensive tackle Kevin Givens to the injured reserve in a pair of corresponding moves. Both Hasty and Givens are dealing with high-ankle sprains.
Hasty has been a valuable backup back for the 49ers over the past two seasons and was primed for a more prominent role following injuries to the team’s top backs.
However, after racking up 59 yards from scrimmage on nine touches (five carries and four receptions) last Sunday against the Eagles, he’ll have to work his way back from an injury before seeing another extended opportunity.
