The NFL and the players' union sent a planner to the 32 teams Monday outlining procedures for the full reopening of their practice facilities, which were closed because of the coronavirus pandemic.

In a lengthy four-part memo to the clubs written by Commissioner Roger Goodell and approved by the NFL Players Association, the league described protocols focusing on screening, testing, infection prevention and treatment for COVID-19, including response for new infections. Also included were instructions on proper facility access, cleaning and disinfecting; physical distancing; hygiene, health education and medical services; food preparation; supplies; and team travel.

No timetable has been set for the return of most players to team complexes — only players rehabilitating injuries have been allowed to enter the buildings. But this is the next major step toward allowing all players back in club facilities.

Goodell ordered all of those facilities closed in late March, and the league has taken small steps toward reopening them. Last week, coaching staffs were approved to return, but only if local governmental rules allowed it.
