The NFL is continuing the process of getting back to work in their respective facilities, and the latest step is coaches allowed in training facilities as early as this Friday.
This per ESPN's Adam Schefter:
In the memo from Roger Goodell, it details how this step of the re-opening process will be handled. Organization's can have 100 personnel in the building at one time, and the coaching staff would count towards that overall count. Coaches who might be at a higher risk should speak with the medical staff prior to returning to work at their respective facility.
