Williams was a healthy scratch this weekend, so it was clear that he had fallen out of favor in Seattle.
Williams, 30, signed a three-year, $18 million contract that included a $3.5 million signing bonus with the Seahawks back in March. He was set to make base salaries of $3.5 million (2015), $5 million (2016), and $6 million (2017) over the remainder of the agreement.
According to OverTheCap.com, releasing Williams will free up $3,833,332 in available cap space next year while also creating $2,333,334 in dead money.
This season, Williams has appeared in 10 games and recorded 46 tackles, one sack, a forced fumble, a fumble recovery returned for a touchdown and four pass defenses.
