It becomes even more concerning with rookies scheduled to report to training camp on Saturday.
"We don't know if there are preseason games or not. We don't know if there will be daily testing, semi-daily testing, etc. We don't know how a potential Covid test would affect contracts, roster spots, etc. Nothing has been agreed upon regarding what training camp will actually look like and how the 'ramp up' period will work."
The union also wants for positive COVID-19 tests to be classified as a non-football injury.
