Washington Redskins defensive end Jarvis Jenkins has been suspended for the first four games of the 2013 season after violating the NFL policy on performance-enhancing substances, the league announced on Friday.
Jenkins will miss Washington home games against Philadelphia and Detroit and road games against Green Bay and Oakland. The 25-year-old defensive end will be eligible to return to the team after the Redskins Sept. 29, Week 4 game at Oakland.
"When I learned that I tested positive for a substance that is banned under the NFL policy, I was shocked and confused. It's an obscure substance that I've never even heard of, and I still don't know how it got into my body," Jenkins said in a statement. "My only guess is that it came from one of the supplements I was taking around the time of the test, even though none of them listed anything banned."
Jenkins told 106.7-FM the Fan in Washington DC that the NFL tells players to only take supplements with a union-sanctioned label on it. The supplement Jenkins took did not have this label.
Jenkins, a second-round pick of the Redskins in 2011, started in 14 of Washington's 16 regular season games last season after missing all 16 games in 2011 with a torn ACL.
"I'm very sorry for the effect of this situation on my teammates and coaches, and I also apologize to my family and all Redskins fans," Jenkins said. "I will be very, very ready to contribute as soon as I get back for Game 5."
Although Jenkins is suspended for the first four weeks of the regular season, he is eligible for offseason practices and to participate in preseason games.
