I'm pretty sure they don't do official injury reports for preseason games, which will make this a little bit more complicated. Let's give it a shot anyway (focusing just on the Chargers), with an assist from Michael Gehlken.

Chargers SS Marcus Gilchrist (hamstring) will miss Thursday's game. Darrell Stuckey expected to start in his place. — Michael Gehlken (@UTgehlken) August 7, 2013

If Gilchrist ends up missing more than one preseason game, I'll seriously start worrying about his chances to start at Strong Safety. Darrell Stuckey starting in his place probably means that Brandon Taylor won't play, but no official word on that yet.

Danny Woodhead hasn't practiced since Friday. Mike McCoy declined to specify reason for inactivity. Likely to miss Thursday's game. — Michael Gehlken (@UTgehlken) August 7, 2013

That sucks. This offense is going to be way different with Woodhead than without, which means him missing this preseason game hurts the "game reps" for the offense as much as it hurts the fans trying to figure out what Ken Whisenhunt is trying to do.

Vincent Brown (hamstring) to miss Thursday's game vs. Seahawks, per source. Precautionary. Expected to play next week vs. Bears. — Michael Gehlken (@UTgehlken) August 7, 2013

No Danario Alexander (former starting WR), no Vincent Brown (expected to be the starting WR replacing Alexander) and no Danny Woodhead? We're going to need to remind ourselves during this game that the offense we're seeing is against the Seahawks is nowhere near a finished product. This like like trying to play basketball with no backboard, no shoes and no ball.

Anybody else

Because the NFL doesn't require teams to report injuries, or when players miss practice, during the preseason...we have to rely on tweets to tell us who might and might not play. There could be any number of players that are too "dinged up" to play but not too "dinged up" to practice. However, those three guys above will probably be the three most important players missing from action for the San Diego Chargers tonight.
