NFLPA Medical Director: NFL Plans to Test Players for COVID-19 3 Times Per Week

Once players return to their team facilities to continue their offseason preparations, they could be tested for the coronavirus about three times weekly, according to NFL Network's Tom Pelissero.

Per Pelissero, NFL Players Association medical director Thom Mayer indicated players who test positive for COVID-19 would be isolated and quarantined. Officials remain hopeful that "reliable saliva testing is available before players return to facilities."

ESPN's Adam Schefter reported June 3 that players are unlikely to be permitted back until the start of training camp, which opens in mid-July. 

To limit the possible spread of the coronavirus, teams will be confined to their own practice facilities. Some franchises traditionally travel to secondary locations for training camp. Joint practices are prohibited as well.

The NFL sent a memo to all 32 teams outlining certain protocols they'll be expected to follow for the foreseeable future:

While the purpose for those guidelines is clear, making them a reality could prove tricky. Baltimore Ravens head coach John Harbaugh went so far as to call them "humanly impossible," while San Francisco 49ers cornerback Richard Sherman questioned how well the NFL can contain the pandemic:

States across the United States have slowly begun relaxing pandemic-specific restrictions, which has allowed for sports leagues to begin planning for an incremental return. That has also resulted in the number of confirmed coronavirus cases to begin increasing again, however.

NFL Network's Ian Rapoport reported Monday that "several" players from the Dallas Cowboys and Houston Texans had tested positive for the coronavirus. Rocky Arceneaux, the agent for Cowboys running back Ezekiel Elliott, confirmed to Rapoport the three-time Pro Bowler was among that group.
