Tyreek Hill exploded Thursday night against the Patriots on a 75-yard pass play for a touchdown. Hill ended up being wide open down the field, so he took some additional time to celebrate and put a peace sign to New England's defenders.

According to a source from ProFootballTalk's Mike Florio, the gesture "should have been a foul for taunting."

The problem with Hill's peace sign isn't the fact he did it, but it's because he did it in the direction of a defender. The part of the rulebook that explains this part of taunting goes as such: "The use of baiting or taunting acts or words that engender ill will between teams. One could argue Hill making that gesture is baiting the Patriots.

Although Hill wasn't penalized for the play, he can still be punished once the league looks over the game. For context as to how much the fine could be, let's look at a case last year involving Odell Beckham Jr. The Giants receiver was fined $24,000 for a taunting penalty in which all he did was exchange words with a defender.

If Hill does end up getting fined, we'd likely have to hear it from him first. The league doesn't announce fines, and we often have to find out through other mediums when players get punished.

The league has laxed up a bit on its celebration rules for 2017, but the first game in Week 1 could set a standard for other players regarding the taunting aspect.
