What happened: Cosmi was ruled out for Week 3 with a concussion, per NBC Sports. The designation removes him from availability for this weekend's game.

Why it matters: Losing a starting offensive lineman forces a reshuffle up front and tests depth against a regular-season opponent. Continuity in protection and the run game becomes the immediate concern with a backup stepping in.

What to watch: Watch for a starting-lineup update and whether Cosmi clears protocol in time for Week 4.
