Commissioner Roger Goodell gave the 32 clubs the go-ahead for limited reopenings as long as state and local municipalities allow them. Coaching staffs and all players except those undergoing injury rehabilitation are barred from the facilities in the first phase of the league's plan.
With such states as California, New York, New Jersey, Washington and Virginia still under heavy restrictions, that immediately leaves nine franchises unable to use their facilities. The Raiders, headed for Las Vegas for the upcoming season, still have their training complex in Alameda, California.
Among the teams taking advantage of using their buildings on the first day they are allowed are the Falcons, Cardinals and Colts.
