Following a comprehensive seven-month investigation into allegations made in a documentary by Al-Jazeera America, the NFL found no credible evidence that Peyton Manning was provided with or used HGH or other substances prohibited by the league’s policy on performance-enhancing substances, it was announced today.

The Mannings were fully cooperative with the investigation and provided both interviews and access to all records sought by the investigators.

Initiated in January, the investigation was led by the NFL’s security and legal teams with support from expert consultants and other professionals. The investigation involved witness interviews, a review of relevant records and other materials, online research, and laboratory analysis and review.

Separately, the NFL’s investigation continues into the documentary’s allegations made against other NFL players, which involve different lines of inquiry and witnesses.
