Bengals quarterback Carson Palmer missed Sunday’s game with an elbow injury, and there has been speculation around the NFL that the injury is more serious than he’s letting on.

But Palmer insists that one game is all he’ll miss, and he’ll be back on the field Sunday at Dallas.

“I’ve already made up my mind I’m playing,” Palmer said Monday. “I’m going to do what I can in practice and do what they let me do, but I’m 100 percent expecting to play going into this game and planning on playing. I’ll probably be limited in practice, but do what I can.”

Coach Marvin Lewis wasn’t quite as optimistic, saying only, “There is a possibility he could play Sunday.”

Palmer said he injured the elbow in the first quarter of the Bengals’ Week 3 loss to the Giants. Oddly, the Giants game was by far Palmer’s best this season. He completed 27 of 39 passes for 286 yards, with one touchdown and no interceptions with the bad elbow against New York. In the two games when he was healthy this season, Palmer completed  25 of 51 passes for 228 yards, with no touchdowns and three interceptions.
