In assessing the Chargers' RB depth chart, Gilbert Manzano of the Southern California News Group writes: "[Justin] Jackson is probably the most talented running back on the team not named Ekeler, but he struggles to stay on the field because of injuries. If he's healthy during training camp, expect Jackson to win over the new coaching staff and earn the No. 2 job." Durability has certainly been a big issue for Jackson, who played in just 16 total games over the past 2 seasons. But we saw Joshua Kelley disappoint and lose playing time as his rookie season went on. Larry Rountree is the only player among the 3 to be drafted by the current regime, but he was just a 6th-round selection. This looks like an open competition for what's expected to be 2 roster spots. Jackson has played well when on the field and brings intriguing upside as an end-of-draft lottery ticket. This should be a particularly good situation in which to be the #2 back, with Ekeler seeming unlikely to get true workhorse-level rushing work.

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.
