The Washington Redskins announced on Monday offensive tackle Jordan Black has been suspended without pay for the next four games for violating the league’s performance enhancing drugs policy

It is unclear which PED caused him to fail the league-administered drug test, or whether the suspension will extend into the playoffs should the Redskins make a post-season appearance.

He will miss the remaining regular season games against Philadelphia and Dallas.

He is the sixth Redskin to be suspended in the last two seasons. Others include Cedric Griffin – who was suspended for PEDs just two weeks ago and will be eligible to return for the playoffs – Tanard Jackson, Trent Williams, Fred Davis and Phillip Buchanan.
