There’s just over a week left before the National Football League’s new season begins, and its already bickering with the players’ union over Covid guidelines.

The NFL Players Association agreed to renew Covid policies for the 2021 season, mainly emulating policies from 2020, including daily testing and mask mandates. However, with the delta variant causing a surge in Covid cases, there are ongoing discussions about mandating vaccines for players.

During a media conference last week, NFL general counsel Lawrence Ferazani said the league welcomes a vaccine mandate for players, which the NFLPA would need to approve. Ferazani was responding to a question relating to NFLPA president and Cleveland Browns offensive lineman JC Tretter, who alleged the NFL never discussed a mandate. Tretter told a Cleveland radio show the time “has already passed” for the league to issue a mandate for players, especially with the season so close.

The NFL said it was confused by Tretter’s comments, reiterating it would favor a mandate for players.
