The 49ers promoted RB Kerryon Johnson from the practice squad to the active roster. He's now eligible to play against the Packers on Sunday night. Johnson joined the team 2 weeks ago. We'll see how big a role he plays in Week 3 -- if he plays at all. But he shouldn't be in fantasy lineups. San Francisco placed RB JaMycal Hasty (ankle) on IR in a corresponding roster move.

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.

Eagles RB Kerryon Johnson is week to week with a knee injury, according to NBC Philly's Dave Zangaro. Johnson already seemed to be behind RB Jordan Howard on the depth chart -- and this injury might kill his chances of making the final roster. Johnson is off the fantasy radar right now.

Lions RB Theo Riddick (knee) is not listed on the final injury report after putting in a full practice on Friday. His return is excellent timing with the departure of WR Golden Tate and his 9.9 targets per game. Riddick should step back into to a sizable role in the passing game, making him a low-end PPR option. His return also puts a dent in RB Kerryon Johnson’s target projection.

Lions RB Ameer Abullah is inactive for tonight's opener against the Jets. After a preseason that found him in the 1st-team mix, this indicates that Abdullah's depth-chart standing has not improved despite a new coaching staff. With no special-teams role, we're left wondering why Detroit bothers keeping the now-veteran back on the 53-man roster. His deactivation can only help rookie Kerryon Johnson's touch count.
