After a seven-month investigation, retired NFL quarterback Peyton Manning was exonerated by the league after an Al-Jazeera report accused the future Hall of Famer of using performance-enhancing drugs.

The league said that they could find no credible evidence that Manning used human growth hormone or any other PED that would be in violation of the league's substance abuse policy.

Manning retired after leading the Denver Broncos to a Super Bowl 50 victory after the 2015 season.
