Under intensive protocol, players and coaches must have negative test results from the day before in order to enter a team facility.
Starting this Saturday, all NFL teams must operate under the league's intensive COVID-19 protocols for the remainder of this season, according to a league memo sent to teams Wednesday afternoon and obtained by ESPN.
Masks or league-approved Oakley helmet face shields at all times in every part of the facility, including on the practice field.
Other protocols include: all meetings held virtually unless outdoors or with pre-approval for indoors; locker room usage discouraged on non-game days; meals served on a grab-and-go basis; limits of 10 players in the weight room at one time.
Teams across the league have continued to report cases of Covid-19 despite safety protocols put in place this season. He urged clubs to use the next couple days to prepare for the change.
Last week, National Football League owners unanimously approved a proposal to add one playoff team to each conference if meaningful regular-season games are canceled due to the virus. Some players, like Buffalo Bills cornerback Josh Norman, have tested positive for the virus and have missed games due to the diagnosis. The Las Vegas Raiders will place almost their entire defense on the COVID-19/reserve list Wednesday after a number of players came into close contact with someone who tested positive for coronavirus. The Rams said Wednesday the team had placed tight end Kendall Blanton, defensive back Jake Gervase and wide receiver J.J. Koski - COVID-19 reserve list.
The NFL believes those measure will help prevent the spread of the virus among teams.
The NFL's reasons for imposing harsher rules include the rise of coronavirus cases in communities around the United States and a review of contact tracing data that determined teams in intensive protocols yield a 50% reduction in the number of close contacts.
