Four red cards, eight yellows, beers tossed at players, McKennie has his shirt ripped and the game is stopped due to homophobic chanting: USA's 3-0 win over Mexico spirals out of control

The United States beat Mexico 3-0 on Thursday night to reach the CONCACAF Nations League final against Canada - but the game descended into chaos.

Four players were ejected and the match was cut short by the referee after repeated homophobic chants.

The referee also showed eight yellow cards, fans threw beers onto the field of play and Weston McKennie's shirt was ripped. 

The USMNT and Mexico each finished with nine players after McKennie, Sergino Dest, Cesar Montes and Gerardo Arteaga received red cards in a fiery second half. 

'These are rivalry games. These are derby games. Things like this happen across the world and in no way am I embarrassed,' B.J. Callaghan said after his first game as US interim coach.

'It comes from a good place. They care about each other so much in that locker room that they're standing up for each other. Sometimes does it have an issue where we take a red card? Yeah, but when you know where it comes from, you can accept it and it's a learning lesson for us.'

Play was halted in the 90th minute because of homophobic chants. When action resumed, 12 minutes of stoppage time were signaled but resumed chants caused Barton to end the match in the eighth minute added minute.

FIFA fined Mexico 100,000 Swiss francs ($108,000) in January for anti-gay chants by fans at two games.

'In terms of the chant, I want to make it very clear first and foremost, for our beliefs and our culture, it has no place in the game,' Callaghan said. 'It has no place in our value system.' 

Mexico fans have routinely engaged in homophobic chants - specifically a chant using the word 'puto', an anti-gay slur in Spanish - during matches and the FMF has received harsh punishments as a result.

Christian Pulisic put his difficult season with Chelsea behind him by scoring a brace in his first start for club or country since April 15.

The winger, who is set to leave the Blues this summer, broke the deadlock in the 37th minute and added his and his nation's second a minute after halftime.

The goals took his tally to 25 in 59 international appearances, including four goals against Mexico. Ricardo Pepi scored the USA's third in the 78th, five minutes after entering.

McKennie and Dest are suspended for Sunday's final.

'I'm upset, the game didn't need to turn into this,' Pulisic said postgame.

'We don't expect this to happen anymore. Now we are missing two good players for the final'

With its first three-goal victory over Mexico in 23 years, the US stretched its unbeaten streak against El Tri to six (three wins, three draws), matching the Americans' longest, from 2011-15.

Callaghan coached his first game as the second US interim coach after Anthony Hudson quit to join a Qatari club.

Folarin Balogun made his debut, starting at forward after the 21-year-old decided to play for the US over England and Nigeria.

The US went ahead when Gio Reyna poked the ball off Montes and then while prone, poked it forward off Jorge Sanchez.

Pulisic burst behind the defenders, took a pair of touches and from the edge of the six-yard box slotted the ball past goalkeeper Guillermo Ochoa.

McKennie started the move toward the second goal with a long pass down a flank to Tim Weah, who crossed. A sprinting Pulisic got behind Israel Reyes and Sanchez, stabbing the ball in with his left foot from six yards.

Montes was given a straight red card in the 69th for kicking Balogun while the two were challenging.

McKennie was given a red card two minutes later for placing a hand on Sanchez's neck during the ensuing arguing and shoving. McKennie left the field with a ripped jersey.

Pepi scored his seventh international goal, taking a pass from Dest, taking a touch and rounding Ochoa. Dest and Arteaga were sent off in the 86th for shoving each other.

Reyna, his hair dyed blond, made his first start for club or country since March 27, also the last time Dest and goalkeeper Matt Turner had appeared in any match.
