In a new documentary from Al Jazeera, Denver Broncos quarterback Peyton Manning, among a number of other well-known professional athletes, is accused of using illegal performance-enhancing drugs.

Within hours of the allegations going public, Manning denied using drugs in a statement to ESPN.

“The allegation that I would do something like that is complete garbage and is totally made up,” he says. “It never happened. Never. I really can’t believe somebody would put something like this on the air. Who said this is making stuff up.”

The Denver Broncos also stood by Manning in a statement to PEOPLE:

“Knowing Peyton Manning and everything he stands for, the Denver Broncos support him 100 percent. These are false claims made to Al Jazeera, and we don’t believe the report.

“Peyton is rightfully outraged by the allegations, which he emphatically denied to our organization and which have been publicly renounced by the source who initially provided them,” the statement continued.

“Throughout his NFL career, particularly during his four seasons with the Broncos, Peyton has shown nothing but respect for the game,” the team said. “Our organization is confident Peyton does things the right way, and we do not find this story to be credible.”

In Al Jazeera’s documentary, titled The Dark Side, alleges that Manning was given a human growth hormone back in 2011 from a pharmacist, Charlie Sly, who worked for the anti-aging Guyer Institute in Indiana at the time.

This was both the same year that Manning underwent neck surgery and the NFL added human growth hormone testing to its collective bargaining agreement. Guidelines for said testing, however, were not agreed upon until 2014.

Sly claimed he had supplied Manning with the drug during a videotaped meeting with Al Jazeera’s undercover reporter, Liam Collins.

In the video, he says that the drugs were always shipped to Manning’s wife, Ashley, so that his name was never connected to the package.

Sly also said that Manning and his wife would visit the Guyer Institute after-hours so he could undergo intravenous treatments.

Manning denies both of these claims.

“Yes, I have been a patient under Dr. Guyer,” he said. “I have had nutrient therapy, oxygen therapy and other treatments that are holistic in nature but never HGH. My wife has never provided any medication for me to take. Ashley and I never attended the clinic together after hours. There were times when I went in the morning and there were times when I went after practice so this thing about `after hours’ is so misleading because it may have been 5:15 pm because their office closed at 5.”

Sly has recanted on the story, saying he was dropping the names of well-known athletes like Manning to try and determine if Collins legitimately was interested in getting into the supplementation business – his alleged reason for speaking with Sly in the first place.

“When I realized Al Jazeera was using a secret taping and Collins as a so-called investigative reporter, I was baffled,” Sly said. “I cannot believe that can happen. That’s why I recanted the story. It wasn’t true and I was trying to pull one over on Collins to see if he had any idea of what he was talking about.”

Sly also named Washington Nationals infielder Ryan Zimmerman, Philadelphia Phillies first baseman Ryan Howard, Pittsburgh Steelers linebacker James Harrison Green Bay Packers linebacker Mike Neal, Packers defensive end Julius Peppers and boxer Mike Tyson as being involved with using performance enhancing drugs. The first three denied the allegations to Al Jazeera, while the latter three did not respond to a request for comment.

Reps for Manning did not respond to PEOPLE’s request for comment.
