Griffin was suspended for the remainder of the regular season, a four-game suspension stemming from a violation of the NFL's performance-enhancing drug policy.
Griffin, 30, has registered 30 tackles, four pass deflections and a forced fumble in nine games this season, operating in nickel situations.
Griffin is a seven-year pro who had played extensively this season for the Redskins.
Griffin's suspension will cost him $294,118, four game checks.
The Redskins could turn toward rookie cornerback Richard Crawford again as well as D.J. Johnson.
