"I felt Daunte played really well for us," Kiffin said, "but with Josh coming back and looking healthy again, we're going to go back with Josh."
The Raiders were 1-3 with Culpepper at quarterback but have dropped their last three straight games and have scored only two offensive touchdowns in that span.
In their last two games, the Raiders were driving for potential game-winning scores in the fourth quarter only to have their hopes die on interceptions by Culpepper. Overall, Culpepper has passed for 817 yards with four touchdowns and four interceptions. He also has seven fumbles.
Whether McCown can do better remains up for debate. He was 1-2 as a starter and had completed 64.7 percent of his throws, but also had five interceptions and owned a mediocre rating of 75.2.
McCown was also booed unmercifully by Raiders fans during the team's first two home games.
"It is what it is," McCown said. "We've got a job to do. We're 2-5. That's what I'm concerned with, that we're 2-5 and we need to get a win and that offensively we need to produce."
