SEATTLE — Tarvaris Jackson led Seattle on three first-half scoring drives, and Terrelle Pryor struggled through his worst performance of the preseason with a chance at earning Oakland's starting quarterback job in the Seahawks' 22-6 victory in preseason action on Thursday.
Jackson led the Seahawks (4-0) 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.
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 job. He was lackluster, completing 3 of 8 passes for 31 yards and an interception for Oakland (1-3).
Seattle won its ninth straight preseason game. Jackson finished 12 of 17 passing for 119 yards and likely locked up the backup job to Wilson.
49ers 41, Chargers 6
At San Diego, Colin Kaepernick threw a touchdown pass to cap his only drive, and San Francisco roughed up San Diego in the exhibition finale for both teams.
Kaepernick faked an inside handoff and then threw a short sidearm pass to Quinton Patton, who deked rookie free agent Marcus Cromartie and completed the 43-yard scoring play.
Coach Jim Harbaugh started the first-team offense of the 49ers (3-1), while Chargers rookie coach Mike McCoy sat his first-team defense.
The Chargers (1-3) had a bad night. Backup quarterback Charlie Whitehurst was sacked four times in the first half and third-stringer Brad Sorensen threw two interceptions in the second half.
San Francisco linebacker Cam Johnson sacked Whitehurst twice and blocked a punt by Mike Scifres and recovered it in the end zone for a touchdown late in the third quarter.
