What happened: Baltimore listed Lamar Jackson as limited in Thursday practice with a back injury. The session doubles as extra snap work with rookie Vega Ioane at center amid line injuries.

Why it matters: Jackson starts at quarterback, so any restriction reshapes Baltimore's Week 4 preparation. Full participation would stabilize the exchange with a shuffled interior.

What to watch: Next practice designation shows whether he returns to full work. Continued center rotation clarifies the Week 4 line.
