Dan Vertlieb, Williams' Vancouver-based agent, told The Canadian Press that Williams is headed to New Orleans.
On Wednesday, Williams and the Ticats reached an agreement to allow CFL's top special-teams player last year to pursue opportunities in the NFL.
Contract details weren't immediately available, but the 25-year-old Williams stands to make much more than the $48,000 base salary he was scheduled to earn this season in Hamilton.
The NFL's 2013 minimum salary is $405,000.
