Peyton Manning is retiring. He informed the Broncos of his decision on Saturday night, reports CBS Sports NFL Insider Jason La Canfora, and there will be an official announcement on Monday. ESPN's Chris Mortensen first reported the news.

Since the Broncos won Super Bowl 50 last month, there have been weekly reports that Manning was going to call it a career. And now, after 18 seasons, 71,940 regular-season passing yards, 539 touchdowns and two Lombardi Trophies, it's a wrap.

Manning will go down as one of the best players in NFL history, and in just over five years, he'll be in Canton, Ohio giving his Hall of Fame speech.

Patriots quarterback Tom Brady posted to Facebook on Sunday afternoon: "Congratulations Peyton, on an incredible career. You changed the game forever and made everyone around you better. It's been an honor."

When it was all said and done, Brady and Manning met 17 times.
