Kerryon Johnson signs with the San Francisco 49ers

The San Francisco 49ers are adding running back Kerryon Johnson to their practice squad (per Adam Schefter)

Fantasy Impact: With Raheem Mostert done for the year, the 49ers have brought in the veteran Johnson as depth. Last year with the Detroit Lions, Johnson ran the ball 52 times for 181 and 2 touchdowns. He spent the summer on and off the Philadelphia Eagles’ roster. Johnson will likely won’t make the Niners active roster unless their backfield sustains another injury Sunday.
