If the teams remained tied after 90 minutes of play during the 2nd leg of the finals, extra time will be used, followed by a penalty shootout if necessary.
The teams will be seeded 2 to 7 (depending on their position at the end of the regular season).
Higher seeded teams play on their home field during the second leg.
