What happened: Lamar Jackson is dealing with a sprained left ankle. The Baltimore Ravens quarterback has only an outside chance to play Sunday against the Atlanta Falcons, sources told Ian Rapoport, after he was scheduled for MRI on ankle.

Why it matters: Baltimore loses its offensive centerpiece if Jackson sits, forcing a reworked Week 5 game plan. Atlanta gains a preparation edge with the starter’s availability in doubt.

What to watch: Watch late-week practice participation and the Friday injury designation for a final game-status call.
