The Panthers are going back to Matt Moore to start this week's game against San Francisco, benching rookie Jimmy Clausen.
"We have struggled on offense since the beginning of the season," Panthers coach John Fox said. "Sometimes it helps to step back and watch, and Matt has had a chance to do that."
Moore was pulled after committing six turnovers in his first two games, but Clausen has been no better.
Clausen has three interceptions but has fumbled seven times, losing two.
For the season, Clausen has a 52.2 rating to Moore's 33.3.
The Panthers rank last in the league in total offense and points per game.
