Manning maintained his record pace of touchdown passes to start the season and finished with 414 yards and four scores for Denver (5-0).
Tony Romo threw for 506 yards and five touchdowns for Dallas (2-3), but he was intercepted by Danny Trevanthan inside the Dallas 30 to set up Prater's winning kick.
The teams combined for 1,039 yards of total offense in the second-highest scoring game in regulation since the NFL-AFL merger in 1970, according to STATS.
