What happened: Commanders quarterback Marcus Mariota suffered a sprained MCL that is now likely to sideline him for the remainder of the preseason, according to Adam Schefter. Mariota first went down during Saturday's preseason game, signaling a right knee issue to trainers before exiting.

Why it matters: The injury removes Mariota from Washington's remaining preseason reps as the roster sets its quarterback depth chart ahead of the regular season. It adds to a run of camp injuries for the Commanders, who are also working through Chase Bisontis' MCL situation.

What to watch: Washington turns to its other quarterbacks for the rest of the preseason while Mariota's knee is evaluated further.
