Onwuzurike (back) participated in team drills during Tuesday's practice, and he should make his preseason debut Saturday against the Steelers, Justin Rogers of The Detroit News reports.
Head coach Dan Campbell said Onwuzurike recently saw a couple of specialists after the rookie was limited by a back injury in practice. However, Campbell expressed optimism about the evaluations, and Onwuzurike subsequently saw his most extensive workload during training camp Tuesday. While it's not necessarily guaranteed that he suits up during this weekend's preseason game, Onwuzurike seems well on track to be ready for the regular-season opener Sept. 12 against San Francisco.
