Quarterback Terrelle Pryor will make his first start in the Oakland Raiders' preseason finale Thursday night at Seattle while the team rests Matt Flynn.
Coach Dennis Allen said Sunday that Flynn has been bothered by arm soreness throughout camp. The 28-year-old has been atop the depth chart since the beginning of training camp and started Oakland's first three preseason games, though he has struggled to move the offense.
Flynn has thrown two interceptions and been sacked three times.
Pryor, who led four scoring drives after replacing Flynn in the second quarter Friday night in a loss to Chicago, has been the Raiders' most effective quarterback so far. He also is the team's second leading rusher with 83 yards on 11 carries.
