Bengals actively looking for new QB

In need of an heir apparent to Carson Palmer, the Cincinnati Bengals engaged the Green Bay Packers in trade talks for the last pick of the draft's first round Thursday night in an effort to acquire a quarterback.

According to league sources, the Bengals' presumed choice was TCU's Andy Dalton.

Palmer earlier this year told the Bengals that he no longer will play for them and desires a trade.

The Bengals and Packers could not agree on the compensation for the 32nd pick, however, so the Packers selected Mississippi State tackle Derek Sherrod just prior to the expiration of the 10-minute clock allotted for first-round picks.

In addition to Dalton, the Bengals have spent considerable time with Arkansas quarterback Ryan Mallett, who also remains available heading into the second round of the draft Friday (ESPN2, 6 p.m. ET).

Dalton appears to be a better fit for the scheme being installed by Jay Gruden, Cincinnati's new offensive coordinator, but one source said that Mallett's big arm is a better match with the Bengals' first-round draft choice, wide receiver A.J. Green of Georgia.

Bengals owner and president Mike Brown has said he will not trade Palmer, but sources say he may consider it if the team secures a quarterback and gets a favorable trade offer.

Several teams such as the Raiders, 49ers, Seahawks, Cardinals and Dolphins are among those that could be interested in the veteran, who was the No. 1 pick in the 2003 draft.
