CINCINNATI -- Bengals owner Mike Brown insisted on Tuesday that he won't trade quarterback Carson Palmer, who wants to leave one of the NFL's least-successful franchises.

Palmer, who has four years left on his contract, told the team in January that he would retire if he's not traded. The Bengals have only two winning seasons in the last 20 years, one of the worst stretches of futility in league history.

Brown said the club will move on without its franchise quarterback. The Bengals plan to hold their first training camp workout Saturday in Georgetown, Ky.

"I honestly like Carson Palmer," Brown said. "He was a splendid player for us. He's a good person. I wish him well. And he is retired. That is his choice. ... I'm not expecting him to be back."

Asked why he wouldn't trade the 31-year-old Palmer and get some draft picks in return, Brown said it was a matter of principle.

"Carson signed a contract. He made a commitment. He gave his word," Brown said. "We relied on his word. We relied on his commitment. We expected him to perform here. He's going to walk away from his commitment. We aren't going to reward him for doing it."
