“We are relaxing our rules on celebrations to allow players more room to have fun after they make big plays. We know that you love the spontaneous displays of emotion that come after a spectacular touchdown. And players have told us they want more freedom to be able to express themselves and celebrate their athletic achievements.”
Goodell was specific in the type of celebrations he’ll allow including: using the football as a prop after a TD, celebrating on the ground and group demonstrations. These demonstrations cannot be directed at an opposing player, hold the game up or be offensive.
