The Lions plan to hire former Vikings defensive coordinator Alan Williams as defensive backs coach, according to a report by the St. Paul Pioneer Press.
Williams worked with new Lions coach Jim Caldwell at two previous stops.
The two first worked together with the Tampa Bay Buccaneers in 2001 with Caldwell coaching quarterbacks and Williams as assistant defensive backs coach under then-head coach Tony Dungy.
They followed Dungy to Indianapolis where they worked from 2002-11. Caldwell was quarterbacks coach until he was promoted to head coach in 2009, and Williams was defensive backs coach for the duration of his tenure with the Colts.
Williams was fired by the Vikings along with head coach Leslie Frazier after spending the last two seasons in Minnesota.
The Lions have two remaining coaching vacancies, quarterbacks and wide receivers.
