Browns rookie outside linebacker Barkevious Mingo has been ruled out for the season opener against Miami, according to Associated Press. Mingo had returned to practice this week on a limited basis after sustaining a bruised lung early in the second preseason game. But he had not participated in any contact drills. The first-round pick was slated to receive reps as a reserve pass-rushing specialist until his entire game came up to speed at the NFL level. Source: CBSSports
