USING OFFENSIVE, INSULTING OR ABUSIVE LANGUAGE AND/OR GESTURES

Question:
While watching the local sports highlights of the recent MLS game between Toronto and Dallas, it appeared that the Referee showed a red card to somebody on the sideline that obviously was not a player or substitute. I think it was in Toronto. Do the local youth leagues supply referees for MLS games in Canada? Seriously, what was going on there, or was the card for a player standing behind the technical area?

USSF answer (July 27, 2010):
The referee showed the red card to Dario Sala, reserve goalkeeper for FC Dallas, after he threw a ball on the field, for using offensive, insulting or abusive language and/or gestures. Hence, this instance was handled correctly by the referee.
