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 -- with a chance at earning Oakland's starting quarterback job -- struggled through his worst performance of the preseason in the Seahawks' 22-6 victory Thursday night.
