The Redskins re-signed Jackson on Wednesday, the team announced.
The signing comes one day after he was re-instated by the NFL. Jackson had been suspended indefinitely for violating the league's substance abuse policy. He ended up missing the past two seasons, and he's missed more than three seasons overall because of violations of the policy.
Jackson was set to make only $700,000 this season, but the Redskins cut him shortly after his reinstatement was official and re-signed him to a cheaper contract, the source said. The details of his new contract have not been announced, but a veteran minimum salary benefit would count $635,000 against the cap.
The Redskins view Jackson as a bonus if he's still able to play. At 28, he's still in his prime but he's played in only 12 games since the start of the 2010 season. He was slated to be the Redskins' starting free safety in 2012 until he was suspended on Aug. 31 that year. Ryan Clark and Brandon Meriweather are the likely starters this season.
Jackson was suspended on two occasions while with Tampa Bay, including one that lasted from September 2010 to October of 2011.
