NFL Conducting Comprehensive Investigation Into Peyton Manning HGH Allegations

DENVER (CBSNewYork/AP) — The NFL says it is conducting a comprehensive review of allegations that Broncos quarterback Peyton Manning had human growth hormone delivered to his house.

There's no timetable to complete the investigation, but it's not expected before Denver plays Carolina in Super Bowl 50 on Feb. 7.

League spokesman Brian McCarthy said the inquiry, which began weeks ago, involves reviews of records, interviews and coordination with other agencies.

Al Jazeera reported last month that an intern at an Indianapolis anti-aging clinic was secretly recorded suggesting that Manning's wife received deliveries of HGH, which is banned by the league. Manning, then with the Colts, was rehabbing from shoulder surgeries.

The intern, Charles Sly, has since recanted his story.

Manning angrily denied using performance-enhancing substances and called the report "complete garbage."

"I really can't believe somebody would put something like this on the air," Manning said in a statement. "Whoever said this is making stuff up."

Sly also linked baseball players Ryan Howard, Ryan Zimmerman and other athletes to the use of performance-enhancing drugs. Howard and Zimmerman filed defamation lawsuits against Al Jazeera earlier this month.
