Jackson joined Washington before last season after spending the first six seasons of his career with the Philadelphia Eagles. Jackson's release coincided with a report stating the Eagles were troubled by Jackson's off-the-field life.
Jackson described Griffin's situation as “unfortunate” Tuesday, according to Michael Phillips of the Richmond Times-Dispatch.
“I have a good relationship with [Griffin], and he's a good guy. He does all the right things,” Jackson said. “This is the game we're in, this is the league we're in. It's the NFL and nothing's for certain. I head to learn that for myself a couple years ago going through my situation. So the best advice I can tell him is just to keep his head high.”
The Redskins have reportedly looked into trading Griffin, and it's possible the team releases him before the 53-player roster-cut deadline on Saturday.
Washington will open its upcoming season—with Cousins under center—on Sept. 13 against the Miami Dolphins.
