49ers GM John Lynch called RB Elijah Mitchell (shoulder) "very questionable" for Sunday night's game against the Packers. We'll see if Mitchell does anything in practice later today -- and then how he's listed on the final injury report. RB Trey Sermon's Week 3 status is also up in the air with his concussion. Trenton Cannon and Jacques Patrick are the only healthy RBs on San Francisco's active roster. RB Kerryon Johnson is a potential practice-squad callup.

The 49ers signed RB Kerryon Johnson to the practice squad. Johnson was a 2nd-round pick just 3 years ago but hasn't been fantasy relevant since his rookie season. He averaged 3.6 and then 3.5 yards per carry for the Lions in 2019 and 2020 -- and was cut by the Eagles this summer. There's obviously opportunity in San Francisco after RB Raheem Mostert's season-ending knee injury, but we wouldn't bet on Johnson capitalizing on it. He's only worth stashing in deep fantasy leagues.

The Eagles waived RB Kerryon Johnson. The former Lion recently suffered a knee injury that's believed to be a sprain. For now, Philly will move forward with Boston Scott, Kenneth Gainwell and Jordan Howard behind Miles Sanders.
