Gregg Williams thanked NFL Commissioner Roger Goodell for reinstating him and he also apologized while taking “full responsibility” for his role in the New Orleans’ bounty scandal.

The NFL reinstated Williams on Thursday morning, and the Tennessee Titans hired him as a senior defensive assistant.

“I take full responsibility and apologize for my previous actions, and I’ve used this year to reorganize my life and put focus on positive energy and positive ways to inspire and coach and motivate in this profession,” Williams said, reading from a statement.

“I’m grateful for this opportunity.”

The league issued a statement saying that Goodell cited several reasons for reinstating Williams, including Williams accepting responsibility for his role in the bounty program, his commitment to never be involved in any pay for performance system and pledging to teach safe play and respect for the rules.

“The commissioner emphasized that Williams must fully conform to league rules and will be subject to periodic monitoring to confirm his compliance,” the NFL said in its statement.
