MINNEAPOLIS -- The Minnesota Vikings have hired Alan Williams as their new defensive coordinator.

Coach Leslie Frazier finalized changes to his staff Thursday, choosing the former Indianapolis Colts defensive backs coach to replace Fred Pagac in charge of Minnesota's defense. The Vikings also hired Brendan Daly to be their defensive line coach, replacing Karl Dunbar.

Frazier and Williams coached together with Indianapolis for two years and were part of the Super Bowl championship team in 2006-07. Williams has been an assistant in the NFL for 11 seasons.

Daly was an assistant defensive line coach under Frazier and Dunbar before leaving for the St. Louis Rams to be the defensive line coach there the past three years.
