What happened: Los Angeles placed Terrance Ferguson on injured reserve Friday because of an ankle injury. The move sidelines the second-round tight end for at least four games.

Why it matters: The Rams lose a young red-zone target after they had already ruled Ferguson out for Week 4. His absence trims a room Los Angeles carried at five tight ends to open the season.

What to watch: Watch how Los Angeles redistributes tight end snaps over the next four games. The next update comes when Ferguson is eligible to return from injured reserve.
