6:58PM: With less than twenty minutes until kickoff, Smith has been nonexistent on the sidelines leading up to the game. Lock has been taking all starting reps in the pregame warmups, and all signs are pointing to Lock starting under center tonight. Smith will supposedly be available off the bench, but after not appearing in warmups at all, he likely will sit through tonight’s game.
5:53PM: Seattle faced the possibility of a second straight contest without Geno Smith, but that will not be the case. The Seahawks’ starting quarterback will suit up for tonight’s game against the Eagles, per a team announcement. 
Seattle is dressing three quarterbacks tonight, so it remains to be seen if Smith will get the start. His availability has been a question mark throughout the week while recovering from the groin injury which left him sidelined for the previous contest. After extra work pregame to test out his mobility, though, he will at least be available in some capacity.
If Smith isn’t able to start tonight, Drew Lock will earn his second straight start of the year. Lock faced a tall task in replacement duty last week during the team’s trip to San Francisco. Still, he performed admirably, completing 22 of his 31 pass attempts for 269 yards and two touchdowns while tossing two interceptions. With Smith being limited in practice throughout the week, Lock has gotten a good amount of run with the starters this week and should be well-prepared to run the first-team offense, if necessary.
General manager John Schneider told the media today that “Smith surprised them with his ability to move in pre-game workouts” after Smith aggravated the injury in practice this week, per Bob Condotta of The Seattle Times. With the Seahawks currently sitting just outside a Wild Card playoff spot at 6-7, and a logjam of 7-7 teams ahead of them, each game is getting closer and closer to must-win territory, so Smith and Seattle have every reason to want him back in as soon as possible.
In the hours leading up to the game, though, only Lock and third-string quarterback Sean Mannion have been seen in warmups. It’s extremely rare to see a player not participate in pre-game warmups then go on and play, but nothing is impossible. The best guess without waiting for confirmation, is that Smith will be available off the bench in case of an emergency situation, but Lock will start the game with Mannion as his backup, officially.
They are not making the playoffs and it does not matter.
They had the #5 pick in the draft, should have traded up and taken Young, Stroud, or Richardson instead of pay Geno to stay average.
Sounds easy, except the teams that took those QBs also desperately wanted a QB. It would have had to be a drastic overpay to move up and that’s usually not a great way to build.
They had the 5th pick they would have just had to use that and possibly the 20th or some 2nds. The Panthers moved from 9th or whatever. Seahawks would not have had to give up DK or Lockett or any key guy.
After that MNF win over Philly the Seahawks are very much alive. Seattle does have to leapfrog the Rams, who have the tie-breaker.
