Commanders QB Marcus Mariota has a sprained MCL in his right knee, AP source says

Washington Commanders backup quarterback Marcus Mariota suffered a sprained medial collateral ligament in his right knee during Friday night's preseason opener against the Miami Dolphins, per a source. The 32-year-old is projected to miss a portion of the regular season, with no specific timeframe provided. Mariota's injury occurred during the game, and it remains unclear how his absence will impact the team's plans for the remainder of training camp at the quarterback position.

Currently, Jayden Daniels is the starter, having been absent from the game against Miami. The only other quarterbacks on the roster are Sam Hartman and rookie Athan Kaliakmanis. Coach Dan Quinn is scheduled to address the media later on Sunday regarding the situation.
