July 25 (Reuters) - There is no credible evidence that future Hall of Fame quarterback Peyton Manning used human growth hormone or performance-enhancing drugs as was alleged in an Al-Jazeera documentary, the National Football League said on Monday.
Manning, who retired at the end of last season after leading the Denver Broncos to a Super Bowl win over the Carolina Panthers, had denied allegations made in the documentary that he took human growth hormone while recovering from neck surgery in 2011.
The NFL said in a statement that the Mannings were fully cooperative with the investigation and provided both interviews and access to all records sought by the investigators.
