The NFL Players Association contends that Jackson shouldn't have to serve a three-game roster-exempt suspension if he's traded. However, the NFL contends that Jackson must serve the suspension regardless, meaning the Pro Bowl wide receiver could miss six games because of a previous three-game ban for violating the league's personal-conduct policy.
It's a critical issue to the trade value of Jackson, who still hasn't signed his restricted free-agent tender with the Chargers and wants a long-term contract or a new team.
The Minnesota Vikings, Seattle Seahawks and St. Louis Rams explored the possibility of dealing for Jackson before the start of the season. Jackson's agents say they had a one-year deal in place with one team -- believed to be the Vikings -- last week, but it was negated when the team and Chargers couldn't agree on a trade.
