The away goals tiebreaker may not be used in Europe anymore, but it's still up and running in Concacaf.

The Concacaf Nations League quarterfinals take place over the next several days, with four semifinal spots on the line.

The quarterfinals will be staged over two legs, with each team hosting a match. If the aggregate score is tied after 180 minutes of play, the team with more away goals will advance.

Away goals scored during extra time do not serve as an additional tiebreaker, so if the teams remain level after extra time, the series goes to penalties.

Per Concacaf regulations, "if the aggregate score is tied after both legs, the away goals rule will apply. If the tie remains level, extra time will be played, followed by a penalty shootout, if necessary, to determine the winner."

That is in contrast to UEFA, which has removed the away goals tiebreaker for its club and international competitions.
