NFL quarterback Peyton Manning has been named in an undercover Al Jazeera probe as one of several star athletes who were supplied illegal performance enhancing drugs from an anti-aging clinic in Indiana. According to the documentary, set to air Sunday, the five-time league MVP received human growth hormone (HGH) in 2011 from the Guyer Institute in Indianapolis while recovering from surgery. The pharmacist caught on-tape naming Manning, among other pro-athletes, has recanted his statement; and Manning has issued a firm denial of the "baseless" allegations.
