CONCACAF used a different rule for its CONCACAF Champions League, employing away goals at the end of regulation of the second leg but not applying the rule at the end of extra time. It has since abolished extra time in that tournament with penalty kicks used if teams are even on goals and away goals after both legs. MLS adopted this version of the rule for its playoffs in 2014. For example, the semifinal of the 2008–09 CONCACAF Champions League between Cruz Azul and the Puerto Rico Islanders had the following scorelines: First leg: Puerto Rico Islanders 2–0 Cruz Azul Second leg, after 90 minutes: Cruz Azul 2–0 Puerto Rico Islanders Second leg, after extra time: Cruz Azul 3–1 Puerto Rico Islanders Since CONCACAF does not apply the away goals rule for goals scored in extra time, the game went to a penalty shootout, which Cruz Azul won 4–2. A similar situation occurred in the 2018 MLS Cup Playoffs, in the second leg of Seattle Sounders FC vs Portland Timbers. After both legs went 2-1, for a 3-3 aggregate (with equal away goals) after regulation time, the game went to extra time. In extra time, both teams scored. At the end of extra time, the away team, Timbers, began to celebrate, assuming their away goal in extra time would break the tie; but the tournament did not apply the away goals rule to extra time goals, leading to a penalty shootout (which Timbers won 4-2). The away goals rule can also apply to forfeited matches. Celtic lost their away tie to Legia Warsaw 4–1 in the 2014–15 UEFA Champions League third qualifying round. In their home leg, Legia brought on an ineligible player which automatically gave Celtic a 3–0 win. The forfeiture meant that the tie ended 4–4, meaning Celtic qualified to the next round, 1–0, on away goals. The away goals rule can also apply to matches played behind closed doors. For the 2019-20 and 2020-21 editions of the UEFA Champions League, although the away goals rule remained in place for these seasons, home advantage was nullified as a result of the COVID-19 pandemic having no home fans for support (empty stadiums) and even being forced to relocate their "home" to alternate venues, leading to UEFA deciding to abolish the away goals rule. Both legs of the 2020–21 UEFA Champions League Round of 16 contest between Porto and Juventus
