Washington Commanders quarterback Marcus Mariota sprains his MCL and is expected to miss the remainder of the preseason after getting injured in the first quarter of Friday’s preseason win over the Miami Dolphins. Multiple reports say he exits the game early due to the injury.

Updates across outlets describe the injury occurring during Washington’s preseason opener, with Mariota’s status initially described as uncertain immediately after he went down. As more information becomes available, reporting converges on the specific diagnosis: a sprained MCL. The Athletic and Yahoo Sports both indicate the injury is significant enough that Mariota is likely to sit out the rest of the preseason.

While the early coverage focuses on his exit and the immediate lack of clarity about how serious the injury is, later reports shift toward a clearer prognosis and expected availability. No source in the provided materials specifies a regular-season return timeline, focusing instead on his expected absence from remaining preseason action.
