"Jenkins is eligible to participate in all offseason and preseason practices and games."
. STATEMENT BY DEFENSIVE END JARVIS JENKINS:
"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. 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.
"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. I will be very, very ready to contribute as soon as I get back for Game 5."
