MINNEAPOLIS — Number 28 came back for the Vikings, but Minnesota fell behind by 27 at halftime and lost 34-6.

Adrian Peterson played for the first time since suffering a torn meniscus in Week 2, but the running back was limited to 22 yards on six carries and had a fumble at the end of a 13-yard run in the red zone.

Andrew Luck completed 21 of 28 passes for 250 yards and two scores for a passer rating of 125.6.

Bradford finished 32-of-42 passing for 291 yards but also threw an interception before halftime. He finished with a passer rating of 84.5 and was sacked a total of five times.

Minnesota scratched the scoreboard with 3:51 left in the third quarter on a 32-yard field goal by Kai Forbath. The kicker added a 51-yarder in the fourth quarter to improve to 12-for-12 on the season.

Luck scrambled for a gain of 8 on third-and-10 to move well within Vinatieri's range.

Indianapolis added a touchdown on its second possession, benefitting from a leverage penalty on Linval Joseph during a 21-yard field goal attempt for a fresh set of downs at the 1. Turbin plunged into the end zone for a 10-0 lead.

Minnesota continued to struggle on offense, and the Colts marched for touchdown drives of 92 yards and 91 yards in the second quarter.
