What can Singletary bring to Rams? (0:50)

LOS ANGELES -- Hall of Fame linebacker Mike Singletary will work with the Los Angeles Rams' defense this season, returning to coaching after a two-year absence.

Singletary revealed the plans in a radio interview Tuesday, and the Rams later confirmed the arrangement.

Los Angeles coach Jeff Fisher hasn't defined a role for Singletary, who is likely to be an adviser to the defense.

Singletary was the San Francisco 49ers' head coach from 2008 to 2010, going 18-22. He was a linebackers coach with the Minnesota Vikings from 2011 to 2013 before spending the past two years out of coaching.

He played 12 seasons for the Chicago Bears, winning a Super Bowl while becoming one of the best middle linebackers in NFL history.
