ESPN’s Jeremy Fowler reports Marcus Mariota suffered a sprained MCL in the Commanders’ Week 4 loss to the Colts.

05 October 2026

The Commanders were forced to go to rookie seventh-rounder Athan Kaliakmanis after Mariota went down in yesterday’s game. Mariota sprained the MCL in the same knee during the preseason, and it would be surprising if Mariota was cleared in time for Week 5’s game against the Giants. If he’s unable to play, Kaliakmanis could make his first career start if Jayden Daniels (elbows) isn’t ready to return. Daniels traveled with the team to London for last week’s game and was limited in all three practices. He seemed close to playing against the Colts, and with the Commanders sitting at 1-3 and their season potentially on the line, it wouldn’t be surprising if he did suit up in a pivotal divisional matchup against the Giants.
