The St. Louis Rams re-signed defensive end William Hayes to a three-year, $10.5 million deal that includes $5.75 million in guarantees, a source told ESPN.com's John Clayton.
The 27-year-old Hayes registered a career-best seven sacks in 2012, his first season with the Rams after spending the first four seasons of his career with the Tennessee Titans.
Hayes joined the Rams last offseason on a one-year, $900,000 deal.
In 64 career games, he has 15 sacks, 147 tackles and four forced fumbles.
