The Bears signed Blasingame to their 53-man roster Thursday, Aaron Wilson of KPRC 2 Houston reports.
The 28-year-old fullback has joined Chicago's active roster after failing to make the team's initial 53-man roster Tuesday. Blasingame has spent each of the last two seasons with the Bears, appearing in 32 regular-season games and playing primarily on special teams (348 offensive snaps and 422 special-teams snaps).
