The Bengals reversed course and negotiated a trade Tuesday that would send quarterback Carson Palmer to the Oakland Raiders, a source familiar with the discussions told The Associated Press.

The Bengals had been adamant that they wouldn't trade Palmer, who hasn't played since the end of last season. The franchise quarterback decided he wanted out of Cincinnati, which has only two winning records in the last 20 years.

The Raiders (4-2) became desperate for a quarterback after Jason Campbell broke his collarbone during a win over the Browns on Sunday. Oakland was left with Kyle Boller as the starter.

If the Raiders hadn't made a first-round pick as part of its offer, the Bengals were content to let Palmer sit out the entire season and consider trading him next year. Campbell's injury changed the scenario.
