The NFL recently clarified its touchdown celebration rules, the specifics and nuances of which have some calling it the "No Fun League." The list of touchdown no-no's — detailed in a video from the league on Friday — include mimicking a violent act, sexually suggestive dancing, choreographed celebrations, spiking the ball, going to the ground and using the ball as a prop. Even if the rules are restrictive, Browns' wide receiver Andrew Hawkins had some fun mocking them during his touchdown celebration on Sunday. Hawkins scored in the first quarter against New England, and made sure his robotic "celebration" was within NFL regulations. How are players SUPPOSED to celebrate a touchdown according to the NFL? Browns WR Andrew Hawkins demonstrates 👏🏽👏🏽👏🏽 https://t.co/dd8qi5CKXQ The detailed regulations came days after Pittsburgh Steelers coach Mike Tomlin asked for more clarification. Antonio Brown, Tomlin's star wide receiver, was penalized for the second time last weekend for pelvic thrusting after scoring a touchdown. The league fined Brown in Week 1 for twerking in the endzone. “We have to get some clarity in terms of what’s legal and what’s not,” Tomlin said last week. “I know (Brown) doesn’t want it to be a negative thing. He wants to provide positive energy for us and entertain our fans. But we have to get detailed clarity on what he can and cannot do.” Senior Vice President of Officiating Dean Blandino, who narrated the regulations video, said the goal is to prevent players from trying to outdo each other's celebrations. Then watch out, NFL. If other players follow Hawkins' lead and start mocking the NFL with their touchdown celebrations, we could be due for yet anothermeta-rule — no celebrations which troll the NFL's overbearing regulations.
