“Randall Cobb had a serious injury last year in a playoff game and I believe, as I think he would as well and the team, that that was caused from him being mic’d up,” Rodgers said. “Because he fell on his mic pack and he had an injury to his insides that kept him out of the game and probably would have kept him out of the rest of the playoffs. The puncture spot, or the injury spot, was directly adjacent to his mic pack.”

Cobb landed hard on his back while attempting to make a one-handed catch late in the first quarter of Green Bay’s playoff loss to the Cardinals. He began coughing up blood on the sidelines and had trouble breathing. He was released from the hospital after an overnight stay and is doing well now.
