Amari Cooper could be in trouble with the NFL after attending an NBA game, according to ProFootballTalk.

Cooper recently attended a Dallas Mavericks game with Dallas Cowboys teammate CeeDee Lamb. Neither player wore a mask at the game. Cooper is unvaccinated, meaning he may face a fine from the NFL for violating COVID protocol.

Per PFT, the NFL COVID protocol states:

“A player who is not fully vaccinated is prohibited from attending a professional sporting event unless he is seated in a separated seating section, such as a suite or owner’s box, is wearing PPE, and there are no more than 10 people in that separate seating section.”

Cooper missed 2 games in November after having COVID-19. He does not have to be tested for 90 days after his positive case, but could still be fined for violating protocols.

The regular season for the Cowboys ends Sunday at the Philadelphia Eagles.
