Mike Florio of ProFootballTalk.com reports that unsigned San Diego Chargers restricted free agent wide receiver Vincent Jackson worked out a one-year deal with a team interested in acquiring him, but that team and the Chargers could not agree on trade terms.

That team was not identified in PFT's report.

The only team that has reportedly had permission from the Chargers to speak with Jackson are the Seattle Seahawks, but the St. Louis Rams emerged on Saturday as a possible destination for Jackson.
