Mariota (knee) did not participate at practice Thursday.
Mariota was forced to miss the Commanders' contest versus the Giants in Week 5 after spraining his MCL in Week 4 versus the Colts, and now his availability for Monday's game at San Francisco is in doubt. Unless he's able to return to practice in some capacity Friday or Saturday, rookie seventh-rounder Athan Kaliakmanis projects to continue to operate as Jayden Daniels' primary backup in Week 6.
