Peyton Manning threw for 304 yards and three touchdowns as the Denver Broncos locked up the top seed in the AFC and home field advantage on Sunday with a 38-3 thumping of the Kansas City Chiefs at Sports Authority Field at Mile High.

Jamaal Charles rushed for 53 yards on 14 carries. He finished the regular season with 1,509 rushing yards, becoming just the third player in Chiefs history to eclipse the 1,500-yard mark. Priest Holmes and Larry Johnson also accomplished the feat.
