Gordon is officially questionable on the injury report. He was a full participant in practice for the first time this week on Friday.
Asked then if Gordon would play Sunday, Chargers coach Anthony Lynn said: "We'll see. I don't want to speak for Melvin, but if he's feeling well I know he wants to play."
Seahawks running back Chris Carson, meanwhile, will be tested pregame and for now is being called a "game-time decision," a source told Schefter.
Carson is officially questionable with a hip injury.
Information from ESPN's Eric D. Williams was used in this report.
