Column: Justin Fields shows promise in his preseason debut. But the Chicago Bears aren’t taking any chances, adding tackle Jason Peters, 39, to fix the injury-plagued offensive line.

The Bears prepared for training camp with the idea that second-round pick Teven Jenkins, whom they traded up to select, would win the job.

Four players — Elijah Wilkinson, Borom, Alex Bars and Arlington Hambright — have taken reps with the first team, and Wilkinson was there for the bulk of the preseason opener.
