Report: Marcus Mariota injured, Athan Kaliakmanis enters for Commanders

Marcus Mariota went to the locker room injured, and Washington Commanders rookie quarterback Athan Kaliakmanis replaced him, according to ESPN’s Adam Schefter on Sunday, October 4. Schefter’s report did not provide a diagnosis, a timeline or any further detail on Mariota’s injury.

Mariota’s early production

Mariota has played three games for Washington in 2026–27, completing 33 of 51 passes for 340 yards and four touchdowns. He has taken three sacks. As a runner, the quarterback has seven attempts for 49 yards, giving the Commanders both passing and rushing production in the available season totals.

The supplied data records Mariota’s passing volume and touchdown output, but it does not include a Keel Impact rating for him. Keel Impact measures the points per 100 possessions a player adds against an average player; no such player-rating figure is available here for either Commanders quarterback.

Washington’s team context

Washington enters this point in the 2026–27 season with a 1-2 record. The Commanders rank 17th of 32 teams in offensive EPA and 29th of 32 in defensive EPA in the supplied team data. Those rankings place the quarterback change within a team profile that has been closer to the middle of the league offensively than defensively.

Kaliakmanis is listed as a rookie quarterback for Washington, but the data has no 2026–27 statistical line for him and records zero games played. Schefter reported that he replaced Mariota; the report does not say what comes next for Mariota beyond his trip to the locker room.
