AROUND THE SHIELD — When Carolina Panthers coach Matt Rhule reported to the first day of rookie minicamp Friday, he did so in the same way he has for practice since the start of the COVID-19 pandemic: masked up, with all of his note cards, play sheets and the like in hand. Midway through practice, he and his staff threw the masks to the ground. The NFL released a memo Friday saying that fully vaccinated individuals — players, coaches, staff and other personnel — will no longer be required to wear masks inside of team facilities, effective immediately. The move comes following similar guidance from the Center for Diseases Control.
