Kelley (knee) was placed on injured reserve Saturday, Daniel Popper of The Athletic reports.

EDGE Analysis

This isn't a shocking development given Kelley hadn't practiced at all this week, and information following the injury Monday seemed to be relatively guarded by the Chargers. Sony Michel appears poised to take over as the team's primary backup, but rookie fourth-round pick Isaiah Spiller could also work his way into the rotation after being a healthy inactive to begin his career.
