The NFL wants teams to come up with a way to distinguish vaccinated from unvaccinated players on the practice field. Some teams are doing it. The NFL Players Association wants none to do it.

“We did not agree to them and think they are unnecessary,” NFLPA president and Browns center JC Tretter said in a column posted Monday on the union’s website.

The NFLPA, as explained over the weekend, wants to minimize the potential for players lashing out about vaccines, fearful that those outbursts will potentially influence others to not get vaccinated. The wristband approach could prompt unvaccinated players to sound off, since it prevents them from keeping their vaccination status private (even though HIPAA has nothing to do with it).
