Here's the statement from the federation:
Following a review today by the CONCACAF Disciplinary Committee, in accordance with Article VI.1b of the 2013 CONCACAF Gold Cup Regulations, it was decided that United States national team head coach Jurgen Klinsmann has been suspended for one match. This decision was reached in accordance with Articles 18.4, 19.1, 19.2 and 20 of the FIFA Disciplinary Code.
Mr. Klinsmann was ejected from the technical area for showing dissent towards the referee by throwing the ball in a violent manner during the CONCACAF Gold Cup semifinal match against Honduras on July 24, 2013, in Arlington, Texas, USA.
His suspension will be served in the USA’s next match, which is scheduled to take place on July 28, 2013, at the Gold Cup final in Chicago.
This decision cannot be appealed in accordance with the FIFA DC Art. 118.
