What happened: Commanders quarterback Marcus Mariota suffered a sprained MCL that is likely to sideline him for the remainder of the preseason, according to Adam Schefter. Mariota had indicated a right knee issue to trainers a day earlier.

Why it matters: The injury removes Washington's backup quarterback from preseason reps behind Jayden Daniels as the Commanders finalize their depth chart before the regular season. The same Mariota who went down during Friday's preseason game now faces missing the rest of the exhibition slate.

What to watch: Washington's quarterback room will be watched for how it handles reps behind Daniels through the rest of preseason.
