Palmer sat out a 20-12 loss to Cleveland on Sunday, the first game he missed since the end of the 2004 season. He hurt his elbow a week earlier in a loss to the Giants, but stayed in that game and practiced for two days last week despite pain in the elbow.
The Bengals decided to sit him out for a game on doctors' advice, giving the elbow time to heal. Palmer indicated Monday the injury isn't serious enough to require surgery.
The Bengals struggled on Sunday behind backup quarterback Ryan Fitzpatrick, who hadn't thrown a pass in a regular-season game since 2005. The Bengals are 0-4 for the first time in six years, with their next game Sunday in Dallas against a team coming off its first loss.
"I've already made up my mind I'm playing," Palmer said. "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 I'll do what I can."
Coach Marvin Lewis is going day by day with his franchise quarterback. He'll see how Palmer's elbow feels on Wednesday, then decide whether to let him practice.
The Bengals expect to get a roster exemption for receiver Chris Henry, who has completed a four-game suspension for violating the NFL's conduct policy. Henry would be allowed to practice with the team this week, but wouldn't have to be added to the active roster.
