Buffalo Bills safety Aaron Williams, who has not played since Week 5 as he dealt with a career-threatening neck injury suffered in Week 2, will not play again for the Bills in 2015 - but will, however, continue to practice with the team for the final two games.

Williams appeared in just three games for the Bills this season, recording 15 tackles, an interception, and three defended passes. The 25-year-old has now missed 28 of a possible 80 games in his five-year career, and the neck injury is still considered career-threatening despite his returning to practice over the last few weeks.

The Bills signed Williams to a four-year, $26 million contract extension prior to the 2014 season, and he has three years remaining on that deal. If he chooses to continue his career, he will likely return to the team penciled in as a starting safety - but the Bills would probably be wise to make alternate plans this offseason.
