Matt Prater kicked two field goals in the final 93 seconds for the Broncos (7-5), who moved into a first-place tie in the AFC West with a loss by the Oakland Raiders. Christian Ponder set Minnesota's single-game rookie record with 381 yards passing, including a pair of touchdowns to Percy Harvin, but his sideline throw with 1:33 remaining was intercepted by Andre Goodman to set up the winner.
Harvin had a career-high 156 yards for the Vikings (2-10), who lost their fourth in a row.
