Sources: Carson Palmer wants trade

Carson Palmer will ask the Cincinnati Bengals to trade him and will contemplate retirement if he does not get his wish several sources told ESPN's Chris Mortensen.

Palmer, the No. 1 overall pick by the Bengals in 2003, was unavailable for comment as he and his wife, Shaelynn, were awaiting the birth of their third child.

A Bengals spokesman had no comment. The team has Palmer under contract through 2014.
