What happened: Ferguson was ruled out for Sunday with an ankle injury before Los Angeles moved him to injured reserve Friday. The Rams also signed Alex Bachman and Larrell Murchison from the practice squad to the active roster, while Aaron Donald and Jaylen Watson remained out for the weekend.

Why it matters: The move removes one of the Rams' early-season pass-game contributors ahead of a road matchup with Philadelphia. It also extends Ferguson's absence into a week when Los Angeles is already missing Donald and Watson.

What to watch: Sunday's inactive list will show how Los Angeles reallocates snaps at tight end and whether Bachman or Murchison are active after the promotions. The Rams' next injury report will also shape how quickly the defense can regain bodies after Week 4.
