RBs Justin Jackson, Joshua Kelley and Larry Rountree all made the Chargers' 53-man roster behind RB Austin Ekeler. It's still unclear how snaps and touches will be divvied between those 3. Jackson was reportedly in the lead for the #2 RB job before hurting his groin in the preseason opener. It'll be a situation to monitor in Week 1.

Lions RB Justin Jackson (hip) is inactive for today’s game vs. the Bears. Craig Reynolds is active as Detroit’s #3 RB, but Jackson’s absence could be a slight boost for RB D’Andre Swift.

Lions RB Justin Jackson (illness) is active for today’s game vs. the Jets. He should continue to serve as the #3 RB behind Jamaal Williams and D’Andre Swift.

Lions RB Justin Jackson has been downgraded to questionable for Sunday's game vs. the Jets due to an illness. He's averaged 4.3 carries and 2.0 targets over the past 6 games, so his absence would open up some opportunity for RBs Jamaal Williams and D'Andre Swift.

The Lions signed RB Justin Jackson. The 26-year-old has flashed over 4 NFL seasons, averaging 5.0 yards per carry and 7.8 yards per catch. But he's reached double-digit carries only 6 times and had trouble staying healthy. It's also notable that Jackson had to wait until August 1 to land a job. We'll see if he can push Jamaal Williams for Detroit's #2 RB job. Jackson's arrival shouldn't impact RB D'Andre Swift's role.

Chargers RB Justin Jackson (groin) is out for this weekend's game vs. the Eagles. RBs Joshua Kelley and Larry Rountree figure to be active on Sunday, but neither is a fantasy option.
