Sam Cosmi (Commanders) Listed Questionable With Concussion

Sam Cosmi, offensive lineman for the Washington Commanders, has been listed on the injury report with a concussion, carrying a Questionable game-status designation. Concussions are a special-case injury — no return-to-play timeline estimate can be responsibly generated from public information alone.

NFL concussion protocol is managed by independent neurologists and follows a mandatory, stepwise clearance process: the player must be asymptomatic at rest, then progress through graded exertion stages before receiving full medical clearance. That process is symptom- and protocol-dependent, not calendar-driven. Until Cosmi clears every step, no one outside the medical staff — including us — can project when he returns. The Questionable designation tells us he hasn't been ruled out, but it does not tell us where he stands in the protocol.

The injury date has been resolved as September 20, 2026, based on thread context. Cosmi is approximately two days into the concussion protocol as of this report. What to watch: any upgrade to Full Practice participation or official clearance language from the team — those are the signals that matter here, not the game-status tag.
