Three things to watch:
Quarterbacks: Russell Wilson will play only a series or two, but Terrelle Pryor should see a lot of time under center as he tries to prove he deserves a roster spot behind Tarvaris Jackson, who is the clear No. 2. B.J. Daniels, who was claimed off waivers from the 49ers last season, hopes to beat out Pryor for that spot; but Daniels has a slight groin strain and his status for this game is uncertain. Daniels hasn’t gotten a lot of practice time in camp because the Seahawks have given Pryor every opportunity to learn the offense and get accustomed to how the team operates. Pryor has the physical tools at 6-foot-4, 235 pounds with 4.4 speed, but it still comes down to how he looks leading the offense in game conditions. Daniels (5-11, 215) is similar in size and playing style to Wilson. Daniels doesn’t have the name recognition of Pryor, the former Ohio State QB, but Daniels also is a superb athlete and it would be wrong to underestimate his chances.
Justin Britt: Somewhat by default, the rookie from Missouri is the starter at right tackle for now. Michael Bowie was expected to challenge Britt for the job, but Bowie came to camp overweight, out of shape and unable to play because of a shoulder injury. The Seahawks released him and signed veteran OT Eric Winston, who has started 119 consecutive NFL games. Seeing how Britt looks in his first game action against NFL players will be the first step in determining if he’s ready to take the job.
Running backs: It’s unlikely Marshawn Lynch will play one week after ending his holdout. But the two men vying for more playing time this season -- Robert Turbin and Christine Michael -- will see plenty of action Thursday night. Most fans consider Michael the heir apparent to Lynch next season, but Turbin has looked better than ever before in all the offseason workouts and training camp. Turbin’s quickness is noticeably better since having a clean-up procedure on his knee in the offseason. Lynch will be the workhorse again this season, but the Seahawks are looking to the future. Turbin and Michael are competing to be the guy who gets more carries this season.
