Washington Redskins offensive tackle Jordan Black has been suspended without pay for the team's next four regular-season or postseason games for violating the NFL policy on performance enhancing substances.

Black's suspension will begin immediately. The Redskins have two games left and at 8-6 are tied with the New York Giants and Dallas Cowboys for first place in the NFC East.

The 32-year-old Black has played in 14 contests this season.
