The founder of an Indianapolis medical clinic said Monday that a former unpaid student intern who claimed that quarterback Peyton Manning used a banned substance in 2011 did not even work at the clinic until two years later, long after Manning had been treated.
Dr. Dale Guyer, who started the Guyer Institute, an anti-aging clinic, said the allegations against Manning were untrue.
Manning angrily denied using performance-enhancing substances shortly after the report, by Al Jazeera, was made public Saturday. It was based on secret recordings of Charles Sly, who named other high-profile athletes and suggested Manning had obtained human growth hormone via mail addressed to his wife, Ashley.
