MINNEAPOLIS (AP) - After leading the Minnesota Vikings to a surprising playoff berth last season, Leslie Frazier has reached an agreement on a contract through 2014.

The Vikings exercised the fourth-year option on his contract Wednesday, helping Frazier avoid what would have been a lame-duck season in 2013 while also giving the team some flexibility going forward.

Frazier was entering the final year of his deal, and talks of an extension started to become an issue publicly as the Vikings mounted a stunning December run to the playoffs. Stuck at 6-6 and without injured receiver Percy Harvin, the Vikings rode Adrian Peterson to four straight victories, including a thriller over Green Bay in the regular-season finale to thrust them into the postseason. They lost to the Packers the next week in the wild-card round.
