Williams has actually never seen the field during a regular-season game since entering the league in 2013 due to knee problems. The Queensland native was on the non-football illness list during the 2015 campaign as he recovered from cancer surgery.
Having surgery back in May of 2015 to remove a kidney after being diagnosed with Papillary Type 2 cancer, Williams battled back to take part in the 2015 pre-season but was then placed on the non-football illness list.
By the Seahawks making this move it will make Williams a free agent and he can sign with any team, if they want to give him a shot at making the roster.
Williams has not had the chance to prove himself at the NFL level, at Alabama he racked up 61 total tackles, 1.5 sacks and three passes defended in 2011 and 2012 for the Crimson Tide as a rotational piece for head coach Nick Saban during two championship years.
At only 25 years of age if Williams can prove himself fit and health a team might give him a shot at building an NFL career.
