Bengals rookie quarterback Andy Dalton returned to practice with his teammates on Thursday. Dalton came down with the flu on Wednesday morning, forcing him to miss an important practice for a playoff game in Houston only three days away. He went to a hospital for treatment to help him recover quickly. "I saw him this morning," cornerback Leon Hall said. "I gave him a hard time about how he looked. He didn't look himself, to say the least." Dalton watched tape of the practice that he missed to get up to speed on the game plan. He took it easy while warming up during the first half-hour of practice that was open to the media. "I can't try to do too much," Dalton said. "I've watched the film and I know what's going on. Obviously I would have liked to have practiced yesterday, but it didn't happen."
