With a retirement announcement from former Tennessee QB Peyton Manning expected to come soon, the Denver Broncos decided to pay their respects to the 18-year career of the future Hall of Famer on Sunday morning.

The team sent out this message on Twitter:

It was reported earlier on Sunday that Manning will make his retirement official on Monday.

The team’s message included comments from several of the most prominent members of the Denver Broncos front office and coaching staff.

Here’s a glimpse at what each had to say about Manning, who spent the last four seasons with the organization:

Broncos head coach Gary Kubiak

“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,” said Head Coach Gary Kubiak. “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.”

Broncos general manager and former QB John Elway

“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, Broncos Executive Vice President of Football Operations and General Manager. “Peyton was everything that we thought he was and even more—not only for the football team but in the community. I’m very thankful Peyton chose to play for the Denver Broncos, and I congratulate him on his Hall of Fame career.”

Broncos president and CEO Joe Ellis

“The Denver Broncos are so proud to have called Peyton Manning our quarterback for the last four years, and we can’t thank him enough for his many contributions to our team and community.

“On the field, Peyton’s competitiveness, intensity and leadership helped us to one of the most successful periods in our history, highlighted by four consecutive division titles, two AFC Championship victories and a win in Super Bowl 50. Off the field, Peyton’s kindness and generosity, especially toward those in need, made a real difference on a very personal level.

“Our team, our organization and our community are all better because of Peyton Manning. He raised the performance of those around him and raised the level of excellence here at the Broncos.

“Peyton’s been a first-class ambassador who did things the right way and had such a positive impact on the Broncos. We look forward to celebrating his future induction into both the Broncos’ Ring of Fame as well as the Pro Football Hall of Fame.”
