EDGE Analysis

Thornton did not play in Saturday's preseason game against the Colts and has been dealing with a hamstring injury the past couple of weeks. The exact severity of the injury hasn't been specified, but the 29-year-old is reaching a point where his expected starting spot at defensive tackle could be in danger with his limited reps.
