ENGLEWOOD, Colo. (AP) — Peyton Manning announced he was retiring at a Monday news conference. 

Broncos coach Gary Kubiak said he's only coached Peyton Manning for nine months "but I'll remember it for a lifetime."

Speaking after executive John Elway paid tribute to Manning's four seasons in Denver, Kubiak said he's spent 17 seasons trying to beat Manning and he "wasn't very successful."

He also told a story about how he had several private meetings with Manning after Week 9 as he came back from injury. The two worked together to make sure Manning's presence helped the team and didn't cause any disruptions.

Broncos executive VP John Elway has now taken the podium to talk about Manning.

"I know this is a tough day for him," Elway said.

Peyton Manning had quite a few big names at his retirement announcement.

There are former teammates such as John Lynch, Jeff Saturday and Brandon Stokley. Demaryius Thomas and Emmanuel Sanders are chatting with Manning's wife and children.
