There was an enormous amount of concern when Brown got carted off the practice field at mandatory minicamp. The Commanders didn't officially disclose the issue, but they treated the Ohio State product with extreme caution over training camp. Brown didn't get any reps during the preseason, which wasn't a great shock in the circumstances. However, the fact that he looked explosive and sharp during an on-field workout before Washington's final warmup game against the Baltimore Ravens represented a positive step in the right direction.
