Peyton Manning threw for 256 yards and three touchdowns, the last to Emmanuel Sanders with 36 seconds left as the Broncos (2-0) appeared headed for overtime. But on the next play by the Chiefs (1-1), Charles was stripped by Brandon Marshall and the ball bounced right into Roby’s hands.

The dramatic about-face came after Knile Davis gave Kansas City the lead with 2:27 left on an 8-yard run, raising hope among a sellout crowd that the Chiefs might finally end some curses. Instead, Denver pushed its winning streak to seven straight over its AFC West rival, while Manning improved to 14-1 in his career against the Chiefs.
