Is this an example of excessive celebration:

I believe I read something that was from FIFA that said jumping over barrier, or in crowd is excessive celebration and warrents a caution.

USSF answer (August 20, 2011):
Scoring a goal is an emotional moment in soccer and appropriate expressions of joy are to be expected. However, the Laws of the Game make clear that such celebrations must not unduly delay the restart of play, nor must they involve actions which are derisory, calculated to demean the opponents, or be offensive to participants and spectators. Although there was mention in the past that leaving the field, jumping over barriers, and entering the crowd was unacceptable, that no longer exists. The referee’s primary concern remains ensuring that the celebrations not delay the restart of play.

Interpretation of the Laws of the Game and Guidelines for Referees (2011/2012 Law 12):

Celebration of a goal
While it is permissible for a player to demonstrate his joy when a goal has been scored, the celebration must not be excessive.

Reasonable celebrations are allowed, but the practice of choreographed celebrations is not to be encouraged when it results in excessive time-wasting and referees are instructed to intervene in such

A player must be cautioned if:
* in the opinion of the referee, he makes gestures which are provocative, derisory or inflammatory
* he climbs on to a perimeter fence to celebrate a goal being scored
* he removes his shirt or covers his head with his shirt.
* he covers his head or face with a mask or other similar item

Leaving the field of play to celebrate a goal is not a cautionable offense in itself but it is essential that players return to the field of play as soon as possible.

Referees are expected to act in a preventive manner and to exercise common sense in dealing with the celebration of a goal.
