The Titans hired Gregg Williams as senior assistant/defense today after the NFL reinstated the veteran coach from indefinite suspension for his role in the Bountygate scandal as Saints defensive coordinator.

Williams started his NFL career with the Oilers/Titans and coached for 11 seasons (1990-2000) for them, including four as defensive coordinator.

“I have known Gregg for over two decades and have seen him work his way up from a quality control coach to a head coach,” Titans coach Mike Munchak said in a statement released by the team. “He will bring a great deal of defensive knowledge and energy to our staff. The decision to bring him here only came after going through a thoughtful and thorough process.”

Williams was Saints defensive coordinator from 2009-2011. After initially denying any involvement in Bountygate scandal, Williams admitted to running a bounty pool of up to $50,000 over three seasons with the Saints that rewarded players with thousand-dollar payoffs for knocking targeted opponents out of games.

Last March, the NFL suspended Williams indefinitely for conduct detrimental to the league. The league issued a statement today:

“Commissioner Roger Goodell today notified Gregg Williams and the Tennessee Titans that Williams’ contract with the Titans has been approved and that he has been reinstated. The commissioner cited several reasons for the reinstatement, including Williams’ forthcoming acknowledgement of and acceptance of responsibility for his role in the bounty program at the Saints, his commitment to never again be involved in a pay-for-performance or bounty system, and his pledge to teach safe play and respect for the rules at all levels of the game. The commissioner emphasized that Williams must fully conform to league rules and will be subject to periodic monitoring to confirm his compliance.”

Williams will work with defensive coordinator Jerry Gray. They worked together previously with the Titans, Redskins and Bills, but in those instances Williams was either head coach (Bills) or coordinator (Titans, Redskins).
