Jackson, who is under a three-game suspension for drunken driving offenses, has been holding out and has refused to play for the Chargers.
A 4 p.m. Wednesday deadline worked out by the league and the NFL Players' Association allowing Jackson to play by Week 5 if he were traded to another team came and went without a deal despite multiple offers being put before the Chargers, sources told ESPN.
The broadcaster quoted a source as saying the Minnesota Vikings offered the Chargers a second-round draft choice and an additional conditional pick for Jackson.
Another source reportedly indicated the receiver had even worked out a financial package with Minnesota.
"We had multiple offers and the Chargers squashed them all," Jackson's agent, Jonathan Feinsod, told ESPN.
