San Francisco 49ers LS Kyle Nelson:
"I have been made aware by the NFL that I tested positive for a banned substance, and as a result will be suspended. I have been taking the same supplements for my entire time with the 49ers, while undergoing often simultaneous testing by the NFL with no issues. I do not deviate from my nutrition routine, and I would never knowingly take a banned substance. I am currently having the supplements tested, and I hope to uncover the cause of the positive test. When the product is identified I fully intend to seek legal action against the manufacturer to protect against this happening to other players in the future."
San Francisco 49ers General Manager John Lynch:
"We are certainly disappointed to be losing Kyle for 10 games. Hopefully this serves as a reminder to all of our players that they need to take the proper steps to know exactly what they are putting in their bodies."
