Seattle will start Drew Lock against Arizona on Sunday after ruling Sam Darnold out with the glute injury that ended his opening game early. Coach Mike Macdonald confirmed the decision on Wednesday, giving Lock a full week to prepare as the starter. The Seahawks do not currently expect to place Darnold on injured reserve, but they have not named a return date. Those are two separate pieces of news: the Week 2 absence is settled; what happens after Arizona is not.
Lock already helped Seattle beat New England 13-10 after Darnold left the opener. That relief performance gives the Seahawks evidence that their offence can function with him. It does not tell us how Sunday's game will unfold against a different opponent, with a different defensive plan and a full start rather than an emergency handover.
What Seattle has confirmed
Macdonald said Darnold will miss the Cardinals game and Lock will start. Jalen Milroe moves into the backup role. The coach said the team will reassess Darnold daily and again next week, while indicating that a move to injured reserve is not anticipated. Seattle does not plan to add another quarterback for this game, according to its own report.
The injury was initially described around Darnold's hip after he exited against the Patriots. The club's subsequent account identifies a glute injury rather than damage to the hip joint. That difference matters when reading updates, but it is not a licence to diagnose the problem or predict a recovery date. The useful public facts are that he cannot play this week, is doing rehabilitation work and will be reassessed.
The fixture sequence puts the uncertainty in view:
| Date | Confirmed position | What remains open |
|---|---|---|
| 9 September | Darnold left Seattle's 13-10 opener against New England; Lock finished the win. | The injury's precise recovery timetable. |
| 16 September | Macdonald ruled Darnold out for Week 2 and named Lock the starter. | Whether Darnold can return for a later game. |
| 20 September | Seattle are scheduled to play at Arizona, with Lock set to start. | The result and how the offence will perform over four quarters. |
| 27 September | Washington are next on Seattle's published schedule. | Darnold's availability has not been confirmed. |
The 27 September date is a fixture, not a projected return. The distinction prevents the team's decision not to use injured reserve from being mistaken for a promise that Darnold will play the following week.
Lock's relief game is evidence, not a forecast
Lock completed 16 of 22 passes for 187 yards and a touchdown against New England, without an interception or lost fumble. Seattle's account gives him a 113.3 passer rating. The fourth-down touchdown to Jaxon Smith-Njigba covered 45 yards in the scorebook, though Smith-Njigba supplied the substantial run after a short pass. Describing it simply as a 45-yard throw would make the play sound quite different.
Lock entered with Seattle trailing and helped turn the game into a narrow victory. The defence also had a decisive role, intercepting Drake Maye three times in the fourth quarter. The comeback is therefore not a one-man proof that the quarterback change solved everything. It shows Lock handled an unscheduled appearance well while other parts of the team created the chance to win.
A planned start changes the preparation. Lock is due to take the starter's practice repetitions this week; Milroe will receive more work as the backup. That should allow Seattle to shape its calls around the available quarterback rather than adjust during a game. It also gives Arizona the same advance knowledge. Neither side can treat last week's relief numbers as a reliable prediction of Sunday's passing total or result.
For Seattle, the practical question is whether Lock can sustain drives when the Cardinals know he is starting and can prepare for his preferences. For Arizona, the challenge is not simply to stop one spectacular play: Seattle won the opener through a combination of a late offensive response and takeaways. Those are football questions to watch, not reasons to declare one team a certain winner.
A short absence is still an absence
Macdonald's decision separates immediate availability from longer-term concern. Not placing Darnold on injured reserve suggests the club does not currently expect a prolonged spell out, but the coach's daily reassessment language deliberately leaves room for recovery to dictate the next decision. Medical progress can be uneven. Until Seattle confirms another selection, any claimed date for his return would go beyond the evidence.
The photograph used with this report shows Darnold at Seattle's February Super Bowl victory parade. It identifies the Seahawks quarterback in his genuine team context, but it does not show the New England injury, this week's training or Sunday's Arizona game. The event shown in an image must not quietly become visual evidence for a later event.
Readers following the wider US Sports coverage will recognise the difference between a confirmed team-sheet change and a projected one. Our guide to NFL overtime rules explains a separate game situation that may matter if a fixture is level after regulation; nothing in Darnold's injury news makes overtime more or less likely. The broader lesson is to use each piece of information for the question it actually answers.
No current odds are quoted here, and the announcement by itself does not establish value in any betting market. Prices can move as team news changes, and a replacement quarterback's strong relief appearance does not remove match uncertainty. Anyone aged 18 or over considering a bet should check the official line-ups and the bookmaker's rules close to kick-off, stake only what they can afford to lose and avoid chasing a result. BetOwl's responsible gambling guide has practical limits and support information.
Lock has earned the start by answering an unexpected call in Week 1. Darnold's status beyond this Sunday remains an open medical and selection question. Seattle's next firm answer will come from the club, not from extrapolating one comeback or a decision to avoid injured reserve.
