"Will has been an integral member of our defense since he became a Ram in 2012," Rams GM Les Snead said in a statement. "His passion set the tone for our defense and served as an example for his teammates. Off the field, he showed compassion as he was a major contributor to the St. Louis and Los Angeles communities, working to improve the plight of the homeless. We wish Will and his family the best of luck in all of his future endeavors."
Hayes logged five sacks in 14 games for the Rams last season.
