If celebrations are deemed a violation by on-field officials, players could still be penalized under existing unsportsmanlike conduct and taunting violations, as well as fined.
"We want to be sure that we do everything right, 100 percent," he said after the meetings. "To have the Super Bowl, that's the important thing."
There is no set time limit on how long such celebrations can continue. But the league is placing an emphasis on speeding up the pace of games. The 40-second play clock will begin once an official signals a touchdown and teams will have to snap the ball for their extra-point play by the end of the clock.

At their regularly scheduled spring meeting Tuesday, the owners also decided to shift the 2021 Super Bowl to Tampa from Los Angeles, where construction delays have pushed back the expected opening of the new home for the Rams and Chargers.

"I actually think it will be easier" for officials to determine which celebrations are appropriate, said Alberto Riveron, the league's new senior vice president for officiating. "But some things will still be open to interpretation."

Former player Jon Runyan, who is in charge of on-field disciplinary actions,Cheap Jerseys USA, will decide the fines. Two other former players, Derrick Brooks and James Thrash will hear appeals for players.
Also approved at the meeting was the Oakland Raiders lease for a stadium in Las Vegas, where the team is expected to play the 2020 season.

Even Commissioner Roger Goodell said he was looking forward to seeing what players would do with their new-found freedom of expression.
The league, however, will continue to penalize any celebration deemed offensive or in bad taste, including those that embarrass opponents or mimic the use of weapons.

Rams owner Stan Kroenke said he welcomed the decision to delay awarding the Super Bowl to Los Angeles by a year.
"I always planned all my celebrations," said Denver's Emmanuel Sanders, already known for his flamboyant TD celebrations, including one that drew a fine last season.
