Griffin underwent surgery in January to repair the torn anterior cruciate and lateral collateral ligaments in his right knee and was expected to miss up to nine months. He said Monday that his surgeon, Dr. James Andrews, gave him the go-ahead to start practicing. Griffin, the 2012 NFL Offensive Rookie of the Year, threw for 3,200 yards with 20 touchdowns and five interceptions last season.
The Redskins open the season against the Philadelphia Eagles on Sept. 9. Their preseason slate of games starts Aug. 8.

Redskins coach Mike Shanahan, who put Griffin through an extensive workout Monday after team doctors cleared his return to practice, would not specifically address questions of whether Griffin would play this summer. But sources who know the coach expressed pessimism Griffin would return in the preseason. One Redskins front-office member said Washington will not want to subject Griffin to any hits this summer. Shanahan also was known in Denver to be cautious with players coming off major injuries.
