The NFL is investigating allegations that Denver quarterback Peyton Manning had human growth hormone shipped to his house in 2011, the league announced Wednesday.
The comprehensive review is not expected to be completed before the Broncos and Panthers square off in the Super Bowl on Feb. 7.
Al Jazeera was the first to report that Manning’s wife received deliveries of HGH, a banned substance by the league, in 2011 while Peyton was recovering from shoulder injuries in Indianapolis.
The report, which was filmed primarily by hidden cameras, inferred that the HGH shipments were intended for the aging quarterback.
Manning has vehemently denied his use of performance-enhancing drugs, calling the Al Jazeera report “complete garbage.”
The 39-year-old quarterback recently mocked the demise of Al Jazeera America, sarcastically telling reporters “I’m sure it’s just devastating for all their viewers.”
