The incident, which followed the sending off of Antonio Valencia for his second yellow card, changed
the complexion of the game, though the USA fortunately escaped with a 2-1 win.
The USA was largely in control, taking a 1-0 lead into halftime, and added a second goal on Gyasi Zardes' tap-in in the 65th minute, but the second half certainly changed in the 52nd minute when Jones was red carded.
The incident began when Valencia took down Alejandro Bedoya in front of the USA bench -- a clear yellow card, Valencia's second of the game, which would have given the USA a man advantage.
But as players from both teams raced to surround Colombian referee Wilmar Roldan, John Brooks shoved Michael Arroyo in the back, so when the Ecuadoran turned around to shove back Jones was right there.
Both players had their hands up. Jones' left got Arroyo in the face, however slightly. Colombian referee Wilmar Roldan didn't see it, but the fourth official, Brazilian Wilton Sampaio did, and Jones was gone for violent conduct.
(Under new IFAB rules implemented for the 2016-17 season, "a player who, when not challenging for the ball, deliberately strikes an opponent or any other person on the head or face with the hand or arm, is guilty of violent conduct unless the force used was negligible.")
Klinsmann did not say whether he had seen replays of the decision, but he did not like it.
"Unfortunately, we lost Jermaine for that incident, which is an absolute joke because it was right there, and the fourth referee made that decision. Not the referee. The referee didn't see it. He followed the advice of the fourth official out there, and it's a disgrace."
