Peyton to announce retirement after 18-year career

Denver Broncos quarterback Peyton Manning will announce his retirement from the NFL at a news conference in Denver on Monday, bringing an end to a career that will surely land him in the Pro Football Hall of Fame, ESPN and nfl.com reported on Sunday. Manning, who turns 40 later this month, will be going out on top after helping the Broncos to a Super Bowl upset victory last month over the Carolina Panthers, the media outlets reported, citing sources close to the quarterback.
