The St. Louis Rams confirmed the hiring Wednesday of Gregg Williams as the team's defensive coordinator.

Reports last month indicated that Williams would be returning to St. Louis after he was set to take over the defense in 2012 until he was suspended for a year by the NFL for his part on the New Orleans Saints' bounty scandal.

Williams returned to the league last year and worked on the Tennessee Titans' staff as a senior assistant/defense before coach Mike Munchak was dismissed in January.

"I am excited about coaching this defense," Williams said. "I would like to thank (coach) Jeff Fisher and the Rams organization for this opportunity and I am looking forward to getting to work and helping our defense become one of the best in football."

Williams and Fisher previously worked together for six years with the Houston Oilers/Tennessee Titans. Williams was Fisher's defensive coordinator for four of those seasons.

"As I've stated before, I believe Gregg is an outstanding football coach and is capable of taking our defense to the next level," Fisher said.

Williams was the Saints' defensive coordinator from 2009 to 2011 before he was suspended for his involvement in the team's bounty scandal.

The Rams' defense finished 13th in the NFL in points allowed and 15th in yards allowed during the 2013 season, but opponents' 68.1 completion percentage was tied for the worst in the league.
