Peyton Manning's retirement from the NFL has been confirmed by the Denver Broncos.

Reports on Sunday suggested Manning was set to announce the end of his illustrious 18-season career the following day, but a subsequent statement from the Broncos confirmed the news.

The 39-year-old had previously been non-committal on talk of him calling it a day after winning a second Super Bowl title following his worst professional season.

However, the Broncos' 24-10 victory over the Carolina Panthers in Super Bowl 50 was indeed his last game.

Five-time NFL MVP Manning retires as the all-time leader in career passing yards and touchdowns having racked up 71,940 yards and 539 scores through the air.

"When you look at everything Peyton has accomplished as a player and person, it's easy to see how fortunate we’ve been to have him on our team," said John Elway, the Broncos' general manager and executive vice president of football operations.

"Peyton was everything that we thought he was and even more - not only for the football team but in the community.

"There's no question that his work ethic is what made him into one of the great quarterbacks of all time. All the film study Peyton did and the process that he went through with game planning and understanding what the other teams did was second-to-none.

"Peyton was a player that guys wanted to play with. That made us better as a team, and I'm thrilled that we were able to win a championship in his final year. Peyton won a lot of awards and set a lot of records, but to me, what he helped our team accomplish during the last four years is what stands out the most.

"I'm very thankful Peyton chose to play for the Denver Broncos, and I congratulate him on his Hall of Fame career."

Broncos coach Gary Kubiak added: "It was a blessing to coach Peyton Manning. Nobody worked harder at the game and nobody prepared harder than Peyton.

"His preparation was the best I've ever seen with how he went about his business. There was nothing like his work habits. Each and every week, he did everything he could to get ready to play not only against the defense but even against the coordinator.

"After competing against Peyton many, many times, I already had great respect for him. But being with him this season, going through what we went through and accomplishing what we accomplished - that was special. He and I battled together and along the way we talked about dreaming that it could end the way it ended. And I'll be damned, it did."
