From Pro Football Talk:
We've heard from two different sources that the Oakland Raiders are willing to trade receiver Jerry Porter, if an interested partner can be identified. One source said that the Raiders discreetly have been shopping Porter for several months.
Porter was a second-round pick of the Raiders in 2000. He received a $7 million signing bonus in 2005, only a day or two before word broke of a trade that sent Randy Moss to the Bay Area.
Porter is scheduled to earn base salaries of $1 million in 2006 and 2007.
Porter would be an instant starter for the 49ers and would add to the rivalry when the 49ers play the Raiders on October 8th.
Update: 7/26/06
This article from ESPN reports that Porter does indeed want to be traded. However, it does not mention any teams that may be interested in the wide receiver.
