Sources: Cowboys, Lions make trade inquiries on Joey Porter Jr.

A handful of teams, including the Dallas Cowboys and Detroit Lions, have begun making inquiries about the availability of Pittsburgh Steelers cornerback Joey Porter Jr., league sources told ESPN.

The Steelers would be willing to listen to trade offers for Porter, according to sources, but they would want a strong compensation package if they were to deal the fourth-year star.

Porter has been seeking a new contract, but the Steelers do not negotiate deals during the season, raising questions about the possibility of a trade.
