SEATTLE -- Dennis Allen knows who Oakland's starting quarterback will be Week 1 in Indianapolis. He's not ready to share whether it will be Terrelle Pryor or Matt Flynn.
"I'm not telling you, but yeah," Allen said. "You've got to think about competitive reasons, too. We'll keep that in house and announce it at the appropriate time."
Tarvaris Jackson led Seattle on three first-half scoring drives, and Pryor struggled through his worst performance of the preseason with a chance at earning Oakland's starting quarterback job in the Seahawks' 22-6 preseason victory on Thursday night.
Jackson led the Seahawks to a trio of field goals from Steven Hauschka, including kicks of 51 and 56 yards. Jackson got the bulk of time in the first half after Russell Wilson made a brief cameo, leading the Seahawks to their first touchdown on their opening drive.
Hauschka also hit from 22, 43 and 53 yards.
While Seattle (4-0) was completing a perfect preseason for the second straight year, most of the attention was on Pryor and his bid to earn the starting job.
Pryor had turned the Raiders' quarterback situation into a real competition with his performance during the preseason. Matt Flynn sat out Thursday with a sore elbow, and Pryor was given an entire half to try and show he deserved the position. He was lackluster, completing 3 of 8 passes for 31 yards and an interception, although he wasn't given much of a chance to get into a rhythm. Seattle had 20:24 of possession in the first half and Oakland (1-3) ran only 19 offensive plays.
Pryor flashed a little of what had his home fans chanting his name last week. On his second drive, Pryor threw darts to Rod Streeter for a pair of 14-yard receptions and later added a 25-yard scramble that led to the first of Justin Medlock's two field goals.
But he was not impressive to the point of making the decision obvious for Allen.
"It's going to be coach's call and whatever he feels is best for the team," Pryor said. "Regardless, at the end of the day, it's all about the team and if it's me leading, I'll lead to the best of my abilities. And we will get things done. If it's Matt leading, he'll get things done too."
Following the field goal, Seattle kept the ball for nearly eight minutes on a 17-play drive that led to Hauschka's 22-yard field goal. Pryor immediately gave the ball back to Seattle, underthrowing Jacoby Ford on a deep pass and Seattle's Walter Thurmond made a one-handed interception. Seattle then had an 11-play drive leading to another Hauschka field goal.
"That pick, I was late throwing it out and that's something that can't happen," Pryor said. "I thought that we were moving the ball and we got three points two times and I believe we could have kept it moving on the first drive, but just have to make that play. Just have to watch the film and understand what we've got to get better at."
Allen said Flynn is expected to be on the practice field Monday after giving his arm a rest. Along with Flynn, Charles Woodson, Darren McFadden, Stefan Wisniewski and Khalif Barnes also did not play.
Asked if he knew who the starter would be, Flynn had no clue. "We'll see," Flynn said. "I can't control anything that happens. I can only control what I do."
Wilson and most of Seattle's starting offense was in for all of three minutes. Wilson hit Stephen Williams for 50 yards on the second play of the game, later scrambled for 11 yards, and finally found rookie tight end Luke Willson for 20 yards. Robert Turbin then capped the drive on a 3-yard run and Wilson's night was complete.
The Seahawks did have two injuries that could have an impact on the final 53-man roster. Williams suffered a concussion on his 50-yard reception, and rookie offensive lineman Michael Bowie injured a shoulder. Both were expected to be on the edge of making the final cuts.
Seattle coach Pete Carroll said he hoped Williams would be healthy enough for the opener -- perhaps an indication his roster spot is secure -- while Bowie's injury could be more serious. Bowie was in a sling after the game.
Seattle also said goodbye to linebacker Bruce Irvin, who will be suspended for the first four weeks for using banned substances. Thursday was Irvin's first significant playing time in the preseason.
"Still sad. I don't even want to take my pads off because I know it's going to be four weeks before I put them back on," said Irvin, who had four tackles and a sack. "I think tonight did me good mentally and physically. I just got to train and bust my butt and be ready when I come back."
