Jordan Black suspended for doping

Jordan Black has been suspended for four NFL games after breaching the league's policy on performance-enhancing substances.

The Washington Redskins tackle made a rare appearance on Sunday, filling in for Tyler Polumbus, who was out with a concussion.

Black is the sixth Redskin to fail a drugs test in the last two seasons.

The 32-year-old will miss the remaining regular season games, and the playoffs should Washington make the postseason.
