OutMarcus Mariota isn't expected to play — the read below describes past games only.

After Daniels injured his elbow on the Commanders' final snap of the second quarter of Sunday's 37-20 loss to the Cowboys, Mariota directed the offense for the second half and finished with 11 completions on 16 attempts for 111 yards and a touchdown to go with three yards on his lone carry. Though a recovery timeline for Daniels has yet to be established while he plans to consult with a number of experts over the next few days before deciding on a treatment plan, the same injury kept him out for seven of the Commanders' final eight games of the 2025 campaign. With that in mind, Mariota could very well be headed for a multi-game run as Washington's starter.

The read

Over his last 9 games, Marcus Mariota has gone over 15.5 CMP 5 of 9 decided times (56%) — versus 56% across the full season. SEA has been a middling matchup for quarterbacks this season, allowing the 13th-most CMP of 32 teams (20.0 per game) (small sample — read with caution). His game-to-game CMP have been moderately variable (σ ≈ 6.0), so short streaks can mislead. These are descriptive stats about past games, not predictions or betting advice.

Hit rate excludes pushes from the denominator. Confidence uses a 95% Wilson interval — a high recent rate on few games still reads as low confidence. Season over rate at this line: 56%.
