The NFL considered imposing limits on team celebrations earlier this year, but instead the league has ruled that only active players can leave the sidelines to join the on-field demonstrations, according to Pro Football Talk's Charean Williams on Monday.
Offenses have been choreographing routines to celebrate scores, and defenses have countered by corralling the entire unit for group photos.
"What started to happen is we had everybody and their family came on the field to celebrate," senior vice president of officiating Al Riveron said at an officiating clinic over the weekend.
"... The rule now says if you're not an actively dressed member of the 46-man squad, you cannot come onto the field to celebrate."
