The AFC North side failed to score a touchdown during their 17-6 loss to their divisional rivals.
The quarterback told reporters: "When we had our chances we didn't take advantage of them. I expect better out of the offense and to not score a touchdown, we've got too good of players, too good of a team to do that.
"For us, we have to watch the film and do whatever it's going to take to fix the issues. We have to move on, we can't let this one hurt us next week. I've got to do a better job of giving [wide receiver AJ Green] a chance to make plays.
"I think that's what he is so good at, when the ball's in the air making plays, when it's him and one other guy or him and a couple guys. When it comes down to it, we have to be better."
The Bengals face the New England Patriots in their next game.
