The Buffalo Bills signed defensive tackle Kyle Williams to a contract extension Friday.

Terms were not disclosed, but the deal reportedly is for one year and $10.5 million, tying him to Buffalo for three more years. Williams, 31, is set to make $4.8 million next season and $7 million in 2016.

The 31-year-old Williams, a four-time Pro Bowler (2010, 2012, 2013, 2014), is the longest tenured Bill and will enter his 10th season with the team. In 2014, Williams played in 15 games for the Bills while racking up 41 tackles, 5.5 sacks, 15 quarterback hits and eight tackles for loss. He has tallied 34.5 sacks in his career — the most by any defensive tackle in team history.

A 6-foot-1, 303-pound LSU product, Williams originally entered the NFL in 2006 as a fifth-round pick (134th overall) by the Bills.
