Bengals offensive coordinator Hue Jackson likes new backup quarterback Jason Campbell, but he said Campbell isn't a threat to starter Andy Dalton's job.
Campbell was a starter for the Raiders when Jackson coached there.
"In no way is he supplanting Andy Dalton. I like our quarterback," Jackson said. "But Jason is a veteran guy who has played in a lot of offenses and has won a lot of games. I think he can help Andy with some of the knowledge that he's picked up. He's that kind of guy. You've got a guy in Jason where things haven't gone all that well for him lately and you've got a guy in Andy that has done well but is still trying to find a way to win in the playoffs. Between the two of them there can be some things gained there."
