The NFL has found “no credible evidence” quarterback Peyton Manning was provided with or used human growth hormone or other performance-enhancing substances, countering allegations made last year in an Al Jazeera America documentary, the league announced Monday.

Manning, the NFL’s only five-time most valuable player, retired this past spring in the wake of Denver’s Super Bowl victory over Carolina in February.

According to an NFL release, the league conducted a “comprehensive seven-month investigation” and the Mannings “were fully cooperative with the investigation and provided both interviews and access to all records sought by the investigators.”

The probe, initiated in January, was led by the league’s security and legal teams with support from expert consultants and others. The investigation included witness interviews, a review of relevant records and other materials, online research, and laboratory analysis and review, the NFL said.

In the documentary “The Dark Side: The Secret World of Sports Doping,” a pharmacist bragged about providing pro football and baseball players with HGH and other performance-enhancing drugs. He implied that Manning, while recovering from four neck surgeries that nearly ended his career, took HGH prescribed by an Indianapolis anti-aging clinic and shipped to his wife.

The NFL said the investigation into allegations made against other players will continue.
