With the Novel COVID-19 virus still going strong and no end in sight, the NFL is still planning to start the regular season on time but if off-season work is all but guaranteed to be shuttered due to the health risks.
It would not be completely unprecedented. The NFL locked out the players in 2011 amid labor concerns and lacking a new CBA. That lasted 132 days before they and the NFLPA were able to get a deal done. That lockout too out almost all off-season work programs and most of the training camp.
On March 11, 2011, the NFL officially locked out the players and free agency were delayed.
