The injury occurred in the 80th minute of the first leg of the round-of-16 tie when Pervis Estupinan delivered a heavy challenge on McKennie, forcing the U.S. international to be immediately substituted.

The U.S. men's national team is trying to qualify for the World Cup in 2022. Mexico, Panama and Costa Rica are the teams that will be playing in the last round of qualification.
