Johnson (ribs) is ruled out for Sunday's game against the Broncos, Darin Gantt of the Panthers' official site reports.
Johnson missed a trio of practices leading up to Week 8 action, and despite saying Thursday that he believed he'd be available versus Denver, the No. 1 wideout officially will be sidelined. Adam Thielen (IR, hamstring), who returned to practice this week, also has been ruled out, while second-year quarterback Bryce Young will start. That will leave Xavier Legette, Jalen Coker, David Moore and Jonathan Mingo as the Panthers' top available wide receivers Sunday, with Johnson's next chance to take the field coming Week 9 against the Saints.
