The NFL has fined Amari Cooper $14,650 for violating the COVID-19 protocols for unvaccinated players by attending a Dallas Mavericks game last week and not wearing a mask, according to a source.

Prior to attending the Mavericks game, Cooper was on the sideline at the Goodyear Cotton Bowl Classic, cheering on Alabama against Cincinnati.

Cooper was with teammates CeeDee Lamb (Mavericks) and Trevon Diggs (Cotton Bowl), but since they have been vaccinated, they do not have the same restrictions and were not fined.

After the regular-season finale against the Philadelphia Eagles, Cooper was asked about being more careful about interactions, with the postseason beginning.

"You don't want to get sick. This is the tournament. We train so hard in the offseason, OTAs, camp, to get to this point. We accomplished that goal thus far," Cooper said. "We're going to do everything we can do to not get sick. If that means isolation, then that's what that means. Hopefully we can isolate enough to not catch it."
