LOS ANGELES (CBSLA.com) — It’s a serious claim that NFL star Peyton Manning strongly refutes.

“Completely fabricated, complete trash, garbage, more adjectives I’d like to be able to use, but it really makes me sick,” Manning said on Sunday.

He is referring to statements in a new Al Jazeera documentary on sports doping.

In the documentary, a hidden camera shows a man indentified as a pharmacist named Charles Sly, describing how the Manning’s would receive banned Human Growth Hormones (HGH) in 2011.

According to the Al Jazeera Investigative Unit, “All the time we’d be sending Ashley Manning drugs. Everywhere, Florida.. Never under Peyton’s name, always under her name.”

Sly claimed that Manning received the drugs from the Guyer Institute in Florida.

However, Dr. Dale Guyer told CBS News that it is, “simply not true,” and that, “Mr. Sly was never an employee of the Guyer Institute and his brief three-month internship occuring in 2013 during which time Peyton was not even being treated,” Dr. Guyer added.

The documentary names several other athletes, but the spotlight has stayed on Manning.

Daniel Durbin, the Director of USC Annenberg’s Institute of Sports, Media and Society says that Manning’s quick and strong response to the claims was smart.

And now, the man seen in the footage, Charles Sly, has refuted his original claims, saying that it’s all not true.

In a YouTube video, Sly says, “There is no truth to any statement of mine that Al Jazeera plans to air.”

“It was not the best produced news report, when you rely on only one source, and that source later recants…” Dr. Durbin added.

Manning will reportedly look to take legal action against those responsible for making the claims.

“I’ve done it the long way. I’ve done it the hard way, and to insinuate anything otherwise is a complete and total joke. It’s defamation and it really ticks me off,” Manning said.
