Unrein spent 2015 with the Bears after signing in Chicago last September upon being cut by the Chargers. The Bears had two UFA defensive tackles from their rotation, with Jarvis Jenkins having met with the Jets recently.
The 29-year-old Unrein played in a mostly reserve capacity last season, although the four starts he accrued were a career-high. Unrein accumulated just three starts in the initial four years of his career.
Unrein looks to be set to spend a sixth season on a John Fox-coached team. The interior lineman spent the first four seasons of his career with the Broncos during Fox’s four seasons there before signing a two-year, $1.9MM deal with the Chargers last season.
