Redskins cornerback Cedric Griffin has been suspended for the final four games of the season after violating the NFL policy on performance enhancing substances, according to a statement by the NFL. Team sources said Griffin tested positive for Adderall.

He will miss the rest of the regular season and will not be paid. He’ll be eligible to return if the Redskins make the playoffs. The fact that the suspension has been announced means that Griffin already has gone through the appeal process.

He’s the second Redskin defensive back to be suspended for drug use this season; safety Tanard Jackson was suspended indefinitely in the preseason for his third drug violation. Last season, left tackle Trent Williams and tight end Fred Davis missed the final four games after multiple positive drug tests.

This hurts the Redskins’ secondary as Griffin was their third corner and had played well of late. There’ a dropoff between Griffin and corner D.J. Johnson and rookie corner Richard Crawford. Griffin’s size helped on the outside and enabled DeAngelo Hall to cover in the slot.

Griffin, who signed a one-year, $1.25 million contract in the offseason, missed three games earlier this season against Cincinnati, Tampa Bay and Atlanta because of a hamstring injury. The Redskins went 1-2 in those games and surrendered multiple big plays.

Griffin’s suspension was announced within minutes after coach Mike Shanahan addressed the media.
