The NFL announced Monday afternoon that Redskins tackle Jordan Black has been suspended for use of performance enhancing drugs. The suspension is for the next four regular season or postseason season games.

It’s the second time in the last three weeks that the Redskins have had a player suspended for using performance enhancing drugs.

On Dec. 4, cornerback Cedric Griffin was suspended by the league. Black’s suspension also is the third drug-related suspension of the year for Washington, and the sixth in the last two seasons.

Just before the start of the regular season, safety Tanard Jackson was suspended indefinitely for violating the league’s substance abuse policy. Last season, tackle Trent Williams and tight end Fred Davis both failed multiple drug tests and were suspended for the final four games of the 2011 campaign. Earlier that year, cornerback Phillip Buchanon was suspended four games for using performance enhancing drugs.

Black has played in every game, mostly on special teams. In Week 3, he filled in at left tackle for Williams, who suffered a knee injury, and on Sunday, he played the entire second half in place of right tackle Tyler Polumbus, who had suffered a concussion.

Black was out of football last season and was close to filing for retirement when the Redskins signed him during training camp. At the time of his signing, he weighed only 275 and needed to gain roughly 25 pounds to get up to playing weight.

The Redskins didn’t send out the statement from the league until after Mike Shanahan had concluded his Monday press conference, so there was no official statement from the coach.

The other two backup tackles on the roster are second-year pro Maurice Hurt, who also plays guard, and rookie sixth-round pick Tom Compton, who hasn’t appeared in a game this season.
