"The San Diego Chargers have rejected several trade offers for wide receiver Vincent Jackson, letting the Wednesday deadline to trade him pass without making a deal, according to multiple sources.

The NFL and the NFL Players' Association had agreed to a 4 p.m. ET deadline for San Diego to trade Jackson, which would have allowed him to be active by the fifth week of the regular season; Jackson is under a three-game suspension for past DUI offenses. When he did not sign his restricted free agent tender, the Chargers placed Jackson on an exempt list, which prohibited him from playing for three more weeks.

By letting Wednesday's deadline pass, the Chargers will keep Jackson on the exempt list for the first six weeks of the season. San Diego still can trade him by the Oct. 19 trade deadline.

"We had multiple offers and the Chargers squashed them all," Jonathan Feinsod, one of Jackson's agents, said."
